This happened to me last night also, I woke up at about 4 in the morning and couldn't stop shivering for like 15 minutes. I had four blankets on and did not feel cold, but I put on a warm sweatshirt and got back under my blankets and that seemed to help. What really seemed to get it to stop was just breathing deep and trying to relax. After a couple of minutes of taking slow, deep breaths I was able to stop shivering and fall back asleep.

BTW...........I think the diagnosis of panic attack is the doctors way of saying the don't know what it is

I have periodically woken about an hour after falling asleep feeling violently cold. I shiver uncontrollably and my teeth chatter. No matter what the season, I feel like I am naked and laying on a block of ice. If I move my legs even an inch, that inch of the sheet feels even colder. I shake so hard that it wakes my husband and he starts rubbing me real hard to warm me up. I am so cold that my muscles are tense and it is hard to relax them because I am shivering so hard. After about 5 or 10 minutes, it goes away and I feel normal again and go back to a sound sleep.

I don't know why this happens. I have asked my doctor and he doesn't have any ideas. I have epilepsy, but they do not think it is related t seizures. One has guessed that my sugar level drops after I fall asleep and another has guessed that my blood pressure drops too low and makes me cold.

Unless they can witness and monitor what I am doing, they don't have a clue.

I was at work yesterday and just instantly got MILD shivers so I put a jacket on which is abnormal for me but I attributed the cold feeling to the rain cooling down outside and the a/c still running in the building. I live in Florida so to go outside in a jacket in August and still be cold was unusual but when I came back in I had some hot tea with a sweet n low and instantly started feeling better. I dont know if it was the warmth from the tea or the sweet n low but either way I felt better. Then around 11pm while I was in bed I turned the tv off and within minutes felt cold to my bone and I was under a blanket and a down comforter which is one comforter too much for me usually. My boyfriend tried warming me up but the shivering was shaking him violently too. I finally got up and into a hot shower which took me about 30 min to warm up, then I vomited and started to feel more like my normal self. I drank about two bottles of water and layed down sometime after midnight. I awoke again around 4am shivering uncontrollably, teeth chattering etc. It hurt to move my body because of the previous tense session of shivering. I finally got to sleep and a few hours later woke up flinging blankets off of me because I was pouring sweat. I dont think for me it was an anxiety attack, I just am not an anxious person. It was very scary for me so I can imagine everyone else.

This has happened to me twice. The first time it passed in about two hours. Several months later it started at 7PM and ended 11PM and restarted at 5AM. At 7AM I was on my way to the hospital by ambulance. Admitted to ER where a blood test was takened and diagnosed a urinary infection which entered my blood stream. Next was a EKG which showed a heart attack had taken place. It took five days to cure the blood infection. Next was a cather and found to have three blocked arteries and aorta valve which led to open heart surgery. Today I feel like a new person.

This happened to me twice last night and Ive just come back from hospital. Its never happened before so I was terrified. Well talking to the 4 different medic people it turns out we are all having PANIC ATTACKS. Thats it ! The brain does some real wierd stuff and this is just one of em . Hope this helps.

Last night I had almost the exact same thing happen to me. It was the only time so far that this has happened to me. I am slightly nervous about going to sleep tonight concerned I might have another episode only worse. I have been looking all over the net and have not been able to find anything that was similar enough to what I experienced until now. I am hoping that it was just what it was and not a symptom of a bigger problem. The only difference from what you reported to have experienced and what I had experienced was that I had initially woken up with my right arm completely numb (I think I must've been laying on it and it "fell asleep") It was very excruciating and took along time for the (normal) feeling to return to my arm and then immediately after that is when my whole body starting twitching slightly, then my teeth started chattering uncontrollably as if from shivering but slightly more intense and I was not cold. It seemed to last for several minutes and during the episode I was still able to do things like surf the net (looking for info on what was happening to me) I had put on extra clothing even though I didn't feel cold and went back to sleep (I do not recall if the attack stopped before I got back in bed and fell asleep or if it stopped after I actually fell asleep) I had woken up again later and was sweating profusely so I removed the clothing that I had put on during the episode and went back to sleep and slept fine after that.

This happened to me last night for the 3rd or 4th time in a decade, give or take. I don't get them regularly, but have often wondered what the cause is--it's so unbearable when it's happening. My whole body was rigid with shaking. I tried not to clink my teeth, but it was nearly impossible. I did not feel cold--I felt HOT most of the time except when I got up to use the bathroom, but kept blankets on me anyway to push through it. Turning on a fan for some cool air on my face and sipping water seemed to help, but only a little.

I did some slow breathing, but what seems to work is just to let it pass--eventually my body tired itself out and I fell asleep. I did get a very dry mouth and my throat burned. My stomach didn't hurt, but I felt like I could throw up just because of the way my throat felt. UGH, so miserable.

I feel okay this morning and have after every episode. Not 100%--My muscles are tired, but I don't feel like I got beat up. I just feel tired for staying up until 2:45 AM with the shakes.

On the web, I've found 2 causes:
1) Anxiety Disorder
2) Low Blood Sugar

I also suspect that extreme dehydration could play itself out this way. I flew home yesterday and planes (and drinking) severely dehydrate you without you feeling the effects.

I also ate right before bed at least 2 of the times, including last night. Not sure how this affects blood sugar...

i had a bad incident last night. i coudlnt sleep so i stayed up until 4 in the morning, which is normal because i stay up late. i recently had a job related work injury and for the duration of my time healing i tend to stay up late. So when i was getting into to bed to fall asleep i started shivering so bad, my teeth were chattering. i woke my girlfriend up and she got me a blanket and sweatshirt. This did not help, my whole body was still shivering and i was so cold still. i then got up and turned on the shower, the temperature was very hot but it still didnt get my body temp. down. my girlfriend then told me to get into the tub. i sat in the tub of very hot water and it helped. The shivering had gone away but i was still very cold. So then i got out of the tub and dried myself quickly and i put on a couple of layers of clothes. i fell asleep but when i woke up the next day my body was so sore. I dont know if this was from me working the day before, it was my first day a new job, which is a physical job. whatever the case is i was very scared, and want to know if anyone has talked to a doctor and figured this horrible event out. Im sorry to whoever else had what i had, its not a fun thing

If there is something to past lives maybe you all were Titanic fatalities? They probably mostly had hypothermia before they drowned? Jes throwin it out there!

if you are taking any medications for the anxiety or depression, this could be a side effect.

My mom started experiencing the violent shivers & stomach pain out of no where. She was told it was Fibromyalgia, but I just am not convinced. This seems to happen to her after stressful occcurences, such as now, the passing of my step-dad. She is now on her way to the hospital and b/c I'm 8 hrs away, I am trying to figure out what could be wrong. She resides in a very small town with a small hospital. My worry is her mentioning she has fibromyalgia and it actually being something else and her not receiving the proper treatment.

From reading all your posts I see no one has received an actual diagnoses & your dr's seem baffled. Wonderful!

UPDATE: After numerous tests & CT scan, the hospital diagnosed my mother as having had an anxiety attack. She was administered 4 medications & sent home. She still doesn't sound the same but said she just needed rest.
Good luck to you all!

Is it normal?
well the only reason Im here is cuz I last night began shivering so intensely for like 3 hours! I seriously almost went to the hospital but instead I went up stairs and took a very hot bath probably 130 degrees hot, im a white dude and I came out red but the shivering stopped and this is the next day and im in such fatigue I can barley move, it hurts to breathe, lay down and sit down! and im really worried it might start happening again and if it does im goin to the hospital, my body might shut down if I went through another 3 hours of that and I already prayed to god it wouldn't happen again cuz that was so messed up- I was trying real hard to breathe slow and calm down but I couldn't! but the hot bath water either put a stop to it or it was a coincidence.
I have never had this happen and does anyone else have this and not know what to do? So far a hot hot bath seems to be a good answer but if it happens agauin im gonna see a doctor cuz im in SUCH pain right now from that.

This happens to me often and for years. I get very cold and shakey when I am in a setting I'm not very comfortable in and decide to chime in on my thoughts and feelings (i.e. Bible study, or other new group) which leads me to believe it's adrenaline/anxiety related, but I'm also feeling very cold tonight and I'm home alone... It seems if I'm emotional about something or not completely comfortable in a setting this will happen to me if I draw attention to myself in any way. My body will start shaking uncontrollably and often I will feel chilled to the bone--even my head will start shaking and I will sit on my hands. I found lately it's happening often in the evenings. I have low blood sugar issues, low thyroid issues, and nervous system/anxiety issues, so this could be attributed to any of these things. I don't wake up shivering at night, but usually go to bed with a heating pad. I've noticed lately around 9PM I start feeling very cold, but this can happen at any time of day and for me usually happens in some type of church group setting when I am trying to express my feelings. I also been diagnosed with an essential tremor and know I have issues with controlling adrenaline. My only guess is that the uncontrollable shaking/shivers and feelings of being freezing is a result of one or a combination of several of my physical health issues. My mother also has Reynauds Syndrom (sp?) so perhaps I've got a touch of that too? I don't take any medication though I was on beta-blockers for a few years for the tremors I've been off those for about a year, so I haven't been on anything but a glandular for the thyroid.

Last night i experienced the most scary thing, in the past i have suffered from just the shaky shivering thing, i used to tremble when i was in an abusive relationship, when i was scared of my partner. But i split up with him years ago. And never had the trembling/shaking since.
Until last night, i was just sitting at home on my computer as i normally do in the evening, when all of a sudden i started feeling nauseous, i had that feeling like i was going to throw up. it continued for about an hour, then i started feeling cold and my hands and feet were very tingly like pins and needles feeling.
Then out of nowhere i started shivering like a maniac, seriously teeth were chattering body was tensing up and my body was just shivering like crazy, and of course i started to panic. My body was covered in goosebumps and i tried to keep warm with covers etc, but nothing worked. I managed to google the symptoms and read about panic attacks but i couldn't concentrate or read it properly.
So i laid down and tried to take slow breaths and instantly it stopped my shivering and the weird feelings and weird thoughts. When i shivered like that i thought i was dying, it was so scary. It was weird because i wasn't worrying about anything at the time, it seemed to just randomly start from nothing.
I had to go to bed early in the end and just keep slow breathing until i fell asleep but i kept waking up feeling weird and had strange dreams and finally woke up after 10 hours sleep and i had been sweating like a pig in the night. Woke up feeling really hungover and had a bad headache. I still feel a bit woozy now, but kind of glad that i figured out what the hell it was, just a panic attack. Still the most scariest thing i've experienced though, hopefully if it happens again i will be able to recognise it and deal with it better.

Hey..
Sorry to hear your having the same trouble. I as well am experiencing periods of absolute freezing even when it's hot out in the morning. Problem is I feel like crap for hours after I get up. Now. I am not a crazy person, don't do drugs or drink. I believe in the ability of the body to self heal. The only thing I can come up with logically is that something we are taking in during the day or night is trying to get out physically. Try a journal and get back to me if you think of anything. I'll do the same. Peace.

I know how you all feel....
I have these shivering episodes i start feeling kind of flu-ish and then i start VIOLENTLY shivering and i cant stop no matter how warm i try to get my body hurts so bad. I learned to take hot
and i mean HOT baths. I just fill the bath up and soak it will stay hot a long time but the moment it cools
i start shivering again so i have to keep filling
the bath up with hot water..i was once in the bath
tub for 8 hours..it just wouldnt stop!
i dont know if this has anything to do with it...
but i do suffer from anxiety and depression
and its from PTSD (post traumatic stress disorder)
and thats from witnessing domestic violence..
its scary and very painfull
i dont have a doctor...but i do have a therapist
i googled shivering for no reason and found this site....i googled it because i feel another episode
coming on right now=[

I had the same thing as described by so many of you, last night. I somehow think this something to do with sleeping on an empty stomach. I braved an hour of these chills, finally woke up and had some bread with a glass of milk and felt better instantly. Please do try this the next time, it really helped.

I've had these once in a blue moon, but my most recent one lasted the longest 1/2 hour!! I get really thirsty with it and when I drink water it usually subsides quicker!!?? This time it didn't though!? Doctors have no clue either, which is really frusturating!The only thing I can pick as maybe causing the latest one was that I had a high protein meal before I went to bed - scrambled eggs - without any carbs!Whether this was the instigator, who know's!! Because of the duration, the next day I felt really sore and spent and a bit nauseous!

This happened to me when i was 12. It was very very scary, i was shaking for maybe 20 minutes, it slowed down after hugging my mom, crying, my dad soothing me, and lots and lots of praying. it didn't slow down to a stop though. nonono not at all. it lasted 20 minutes, violent shivering, then slowed down for the next 15 minutes. it felt like hours. it was 2am or so. it was SO scary, i could NOT stop on my own will. so i confessed all my little secrets to my mom. i told her everything. i told her how i feel about that one guy, how i feel about school, how God's mysteries make me so confused and small.
i have not shivered like that till last night. last night's only lasted for about 2 minutes. i was half asleep and i woke up at 12:33am. i was mumbling things from the book i read an hour ago before i went to bed, while singing the piano music i was playing last night and having random pictures flash in my brain. i felt light headed and dizzy. my head hurt and it felt cool on the inside, like cold fog was squeezing the breath out of me inside out. i was shaky, fingers, legs, then i started to vigorously shiver, my teeth about to break. i thought of him comforting me, wished he was there, prayed and wrote a little in my journal. then i crawled back into bed and fell asleep. scary. i think it's because i worry and think too much. it's probably a teenager thing. i am not on drugs or drinking, and i never will be.

I too suffer from violent shivering. It mostly happens when I am trying to wind down for the night in bed or I am rudely awakened with a rapid heartrate and this shivering. Unlike a lot of you, my husband downplays the whole thing and just tells me to relax. I have suffered from irregular heartbeats and anxiety, but this is a frightening new symptom. Last night my episode lasted for hours and today my legs feel like rubber and I am exhausted. What is wrong with us?

For the past couple weeks I've been having possible anxiety problems.. It got bad enough 2 times that I went to the hospital, So this happened to me this morning. I was shiviring so bad I thought I might bite my tongue or something, so I put my blanket in my mouth so it didn't happen (I remembered hearing to bite down on something before if you are shivering really bad) anyway as I was breathing into the blanket I started to feel a whole lot better. I really believe this, and actually all my other symptoms, is being caused by hyperventilation which can be caused by anxiety or even drinking so next time maybe try breathing into a bag or do what I did and bite down on your blanket and breath into that... Hope this helps

I suffer with the same thing from time to time. Sipping water, propping myself up in the bed are two things that help. I have had diabetes tests and have started to isolate it tomy diet. When I eat alot of gluten food I get stomach things and then this violent shaking and teeth chattering thing that wakes me in the middle of the night. I think not enough water and diet are two good places to start to consider ? Give it consideration.

ALL of you seriously need to start paying attention to things that will accumulate over a period of years and wont EVER leave the body........
lead.....
mercury......
aluminum........
Heck, even TEFLON is used at making bombs. Would you eat off of a pan with packed and fluoridated gunpowder?!?!

I now have Fibromyalgia and Rheumatoid Arthritis thanks to some overexposure of mercury, lead, and aluminum simultaneously.

Learn how to Google people. All of your symptoms line up with lots of other people's. And doctors "know" how to treat it. Convenient. Someone's doing they're chemistry homework......

LIKE THAT LITHIUM WOULD STICK TO AMALGAM MERCURY AND MAKE SOMEONE UNSTABLE STABLE, IE BIPOLAR.

Less than a year ago, I was a perfectly healthy vegetarian. Now I barely hang on to life at 10,000 calories a day and NEVER feel good. Oh, and uncontrollable shivering starts at 50*F.

And you'd better get used to it people; you already assume that I'm wrong and will never find an answer even close as a result.

Those pretty colors on your plates? Lead. Those "silver" fillings? 50% mercury. And I'd say something about Aluminum, but I'm sure you've all been snowed on that one already.........

It sounds like you have an anxiety disorder. I know it sounds strange, and you probably dont feel all that anxious, I just know someone with the exact same symptoms.

i get the same thang ts relly werid

To the person who posted the original comment did you ever find out what the problem is. I to have been having the same problem since I was 19. I am 27 now and it's still happening. i use to have very bad nitemares almost every day before this, but now I don't get them as often if any. For years I was trying to find someone with the same problem. Now all of a sudden I type in "wake up shivering" in google and I came to this site. I tried asking my doctor but she kind of looked at me strange. Any suggestions?

Same here...its been happening this past month...wake hot feeling usually from a "wierd dream" but not a full blown nightmare and then feel strange and shiver or shake with elevated heart rate . Shake or shiver seems to originate in abdomenand then arms. Ive been diagnosed with Generalized anziety disorder so I have the feeling that it is intertwined with the host of other horrific symptoms associated with anxiety which have mostly started for me just this past year...uuugh

I usually take a tiny dose of ativan and it calms me ...

its been happening to me too the last week.
it comes when i wake up and reoccurs as the dy goes on.
its physically painful, i cant control it and my teeth chatter so bad i put a cloth over it!
ugh any help? it hurts my spine.,

Ok I have something to add to this. This may sound bad but I only get these shivering attacks when I am drunk. I know the most logical fix for my problem is to stop drinking. But I'm really more worried about why it happens when I'm drunk. I never had an episode before I started drinking and as a matter of fact the first time it happened was the first time I got drunk. It doesn't happen every time and I don't drink that often so it's only happened to me maybe 5 times in the past 3 years. But last night was the worst it's ever been. I was shivering violently for nearly 3 hours straight, I couldn't sleep I was shaking so bad. This morning when I woke up my whole body was stiff and sore from shaking so much and so long all night. I feel like it might be anxiety or panic attacks because it typically happens after I have been upset during the day. For me I might be a physical reaction to an emotional issue. This is just my thoughts, it's why I started looking for answers because I feel like I have some emotional problems.

This happened to me for the first time last night. I woke up about 2 in the morning shivering uncontrollably, but I didn't feel in the least bit cold, the room wasn't cold, I wias well covered by a warm duvet, etc. It lasted about 5-6 minutes and I think I actually fell back to sleep before it ended.

I was very thirsty with it as well, though that may not be connected since I have a tendency to sleep with my mouth open which can dry your mouth anyway.

The only thing I can think of is that I was out last night and had quite a bit to drink. Having said that, I certainly have been more drunk than that before and I've been drinking alcohol for 15 years now and this has never happened before.

I did used to get panic attacks in the past that usually happened at night before I went to sleep, but I haven't had one in a few years. I'm not on any medication. Also, I tend to have "stress-related" symptoms in general. I have irritable bowel syndrome, I get back pain and I grind/clench my teeth in my sleep. So I'm guessing this is another stress related symptom, though I've not encountered any specific stressful events recently.

I think right now I'm not overly worried about it, but will have to wait and see if it happens again.

This same thing happened to me tonight. I woke up with a slight chill, then just started shivering uncontrollably, but wasn't cold. I was in bed with 3 thick blankets around me trying to make it stop. It seemed that i could only make it stop if i tried completely taking my mind off of it or tried to calm myself. Which was very hard because my body ached so bad. I eventually fell asleep, but i woke again about an hour later and felt like i was going to throw up and my skin was so hot to the touch. I ended up getting a hand towel and ran cool water on it and put it to my face to cool it down. Then i went outside because the air was slightly cool and it definitely helped. Then i got one here because i was kinda of scared, its never happened to me before and i had no idea what it could be. I read a comment farther up that said maybe dehydration? That could be it because Ive been in the sun a lot the past week and maybe i was dehydrated and didn't know it. And I was just wondering if this only happens to wake people in their sleep or what? I hope this doesn't happen again to me because my body is just hurting so bad from it. And i am sorry for everyone else who has to suffer through this with no real answers about what it could be from.

I am so glad to have found this page! I'm also glad to know I'm not the only person having these night time hypothermia. At least once a week I wake up at night and have this problem. Usually what happens is I'll get up to use the bathroom and while washing my hands I'll suddenly get a severe attack of the chills...almost violently! I can crawl back into bed where I'll shake uncontrollably for about 5-10 minutes. I'll turn my electric blanket onto high and that will usually get me back to sleep again but then I wake up the next morning absolutely soaked in sweat. This is a year round situation and I live in LA which means I'm getting these attacks even when it's 90 degrees in the summer!
I am currently on medication for bi-polar and have ptsd from the Navy...which makes me wonder if the diagnoses from other sufferers that it might be anxiety related is right. Hmm...
I'm 35 years old, a female and at 19% body fat so I'm not out of shape or have any physical issues so I'm assuming this is mental...
I do also experience night terrors and wake up an average of once a night and have difficulty recognizing where I am for a few minutes. Are these two possibly related? However, the waking up night terrors and the shivering do NOT happen at the same time.
Any thoughts?

I have been experiencing on and off for months. I shiver so violently that i can not even hold a glass of water. My jaw aches from chattering teeth, and i swear i can feel my organs tense up. Yesterday i went to the emergency room and it was discovered that i have a severe kidney infection. My mom said the same thing happpens to her with a uti. Perhaps its related to the infection.

Ive been searching online pretty much everyone in the world goes through what i do.. has anyone gotten an answer by a doctor? Ive been trying to ask my doctor but i really havent had time off from work so i try to live around. But like in the middle of the night i wake up shivering,with the feeling of throwing up but yet i dont and my stomach sometimes hurt. But useually i get up walk around the house or i go out to the yard and take a few slow deep breaths. Theres times where it lasts a min to maybe 5 mins shivering and what not. Tgeres time also where i feel like i cant breath well.. but i need ti see a doc asap but i need that time to do so cause imt starting to get annoyed and a lil afraid of it. If anyone finds out why this happens please reply.. thanks.

Uncontrollable and violent shivering are an indication that something may be wrong with the body. A sudden, and very high fever causes the body to shake violently. This is called "rigor." When rigor occurs, the body is attempting to warm itself, but it is also attempting to kill the bacteria that is causing the sudden raise in temperature.The human body attempts to recover itself in any way possible. Shivering is an involuntary reflex that means the body could be trying to fight off infection or getting excited. Shivering is normal, but violent shivering can be an indication of the body in trouble.

So glad i found somebody else with this problem; it literally happened fifteen minutes ago, at about 2:55am. I was trying to sleep but i was having bad abdominal pains followed by nausea, and i had a really strange feeling when i was breathing. I would feel sick, my guts would rumble and hurt, and then when I inhaled it would feel like the breath went all the way to my feet, not just my lungs. I got up to go to the toilet (i sometimes just go sit in there when i'm in pain) and after five minutes the pain in my gut stopped and the shivering started. It was so violent that i almost couldn't sit on the toilet (funny, i know). It wasn't like the shivers you have when you're cold, because i a. Wasn't cold, and b. It felt like it came from inside my chest and guts, not on the surface. It went on for five or six minutes, and now i have a headache, i feel incredibly cold, my nose is running and i ache from head to foot. Im wondering if it was some kind of seizure, i've never had a seizure before and neither am i epileptic.

I'm so glad I'm not the only one!This has only happened to me twice. About a year ago on a random night I got these weird uncontrollable shivers, very scary and intense. About a week or two after that I was put on anxiety medicine(not because of the shaking). It went away for awhile but last night the same exact thing happened.Yesterday all day long I felt pains in my joints and muscles like I was getting the flu and this morning after this attack I felt very weak and shaky throughout the day. This has happened both with and without the medicine and I don't know why.

I am a 68 year old female who occasionally suffers from this violet night shivering. I have tried to listen to my body over the years that it's been happening. I do believe that alcohol after a certain time in the evening and eating too late before bed seems to set off my symptoms. Dehydration is a definite. If I hydrate myself all through the day, it really helps. I would also throw anxiety in there too. Other times, I wake up very calm for no reason and know that something is about to happen. Very soon my heartbeat goes haywire and just about jumps out of my chest. I get up and try to breathe deep and slow, have a cup of hot tea with sugar and walk around the house. It can be terrifying since I live alone. You'll never believe this, but eventually I pass a lot of gas and then everything relaxes and calms. So......I would attribute most of these episodes to gastric disturbances and diet. Like one of the other members, I take a small dose of Ativan and that helps me to rest and get back to sleep. Oh and I might add that I have had my heart checked in every way. No attacks or other diagnoses. My advice?....eat healthy, limit fat and alcohol, stay hydrated, and work on your stress. Best of all...breathe deeply often during the day.

Last night, around 10:00PM, I was laying in bed with my wife just watching TV. I was very relaxed and had no stress or anxiety. Aside from working pretty hard yesterday all day long, I hadn't done anything out of the ordinary. We had inadvertently left our bedroom light on, and my wife asked me to get up and turn off the light. As I got out of bed and walked to the light switch, I suddenly began to shiver uncontrollably, even though I didn't feel particularly cold. I got back in bed and rolled myself up in my blanket. It was really strange, because my natural instinct told me that I was freezing my butt off, yet being in the toasty bed did nothing to stop the shivering. For about 10 minutes, I actually thought my teeth might break. I felt as if I was cold, but I know it wasn't cold in my room. It really started to scare the crap out of me, and then it just seemed to gradually diminish until it was gone. It appears I have no other ill effects from having experienced this last night. I sure do hope this was the one and only time I get this. I feel for everyone who has written about this occurrence. It was definitely one of the worst experiences of my life!

I get the extreme cold, waking up shaking so violently it was actually painful and a few minutes later drenched (and I mean sheet, pillows and underblanket changing drenched). Last doc said "panic attacks", now I know what I was dreaming about at the time, I was hardly having nightmares and I've never woken from a nightmare sweating. New doc and a work up later and turns out I have POTS which can cause chills, it got worse after a recent operation so more blood tests where he found my eostrogen had dropped in response to surgery causing the sweats and shivering to get worse. I have also had these symptoms with infection so it's worth getting checked out.

I tried lots of things all of which worked to some extent, (obviously antibiotics for infection) panadol - I sometimes get a low grade fever with it, or ditropan - reduces sweating, or sleeping tablet - I sleep through it, and electric blanket - I can't warm myself otherwise, I never drink alcohol - it does it to me every single time.

I've been having this (Anxiety/Panic Attack) Thanks guys for sharing. All I can say is that, its all in our head. Fight it! Just stay calm, warm yourself up, drink hot tea w no caffeine, stay away from caffeine, breath, stay away from any high stimulant food and most of all PRAY!

Lord, pls help all of us here who's suffering from Anxiety/Panic Attack.Forgive give our sins and thank you lord for making us stronger everyday! Open our mind AND HEART to you Oh LORD! We truly love you!

this happened to me for the first time, just last night. i woke up at 2 something in the morning, and felt cold. i went to use the washroom and get a drink of water. as i walked back to my room, my teeth started chattering REALLY loudly, and i was so cold. i went back into bed and was still very cold, so i layered two big blankets over myself. i even put my head under. then i fell half-asleep, but even with the two big blankets, i still felt shivery, yet i was sweating. i started shaking SO violently, and i was half-asleep, half-awake- and dreaming. as i shook, i dreamt that i wasnt the only person there, that it was a club and we were all shaking.... i cant describe it, im sure you all know how dreams are weird and you cant describe them. i was still half-awake, and shaking so hard, and i tried to stop, but i couldnt help it. i had the worst sleep ever. i woke up in the morning at 6 am, which is weird because i sleep in late. now i think i might have a fever. in the moring i woke up with a cold sweat.

I highly doubt that it is just caused by the materials you intake from everyday use. I am a healthy, ninteen year old caucasian female with no allergies as of now. I rarely ever go to the doctor's but have recently as I started having these violent shivers. I only have them at night, there is no pattern to what days they will happen. When they happen, I feel slightly nauseous and feel extremely weak, and they persist for an hour to several hours. My teeth chatter and I have mild muscle spasms; the first night they had happened to me, I was afraid I was having seizures. The only way I can find relief is by curling up in a ball, laying mostly on my stomach, try to relax, and wait until they go away. I believe they may be partially stress-induced as they only seem to happen when I am under serious stress.

Perhaps it is a problem with my thyroid as hypothyroidism runs in my family, but I was very recently checked for that and all my levels came back perfectly fine except for my b2, which I take supplements for. I wish everyone can find out what is happening with them, my grandmother told me that people shiver when they need something so perhaps it is dehydration, hunger, stress, or a deficiency.

Happened to me for the first time last night right as I was taking my clothes off getting into bed around midnight. I am 23 years old and never had any major health issues. Uncontrollable shivering for what seemed like 20-30 minutes. At first I just went with it and tensed up trying to fight it but after 15 minutes of this I started getting nervous as it seemed to be getting more intense. I turned on all the space heaters and wrapped myself up in blankets and cuddled with my thankfully warm kitten. I started breathing slowly, taking deep breaths and eventually went away. At about 3am I woke up COVERED in sweat. Went back to sleep, woke up at 8 to get ready for work and felt perfectly fine.

The only differences in my day yesteday were that I waited until about 10pm to eat dinner (normally eat around 6 or 7) and I was really high when I got into bed. Normally I don't smoke so close to bedtime but my friend was hanging out and convinced me to right before he left..

I never drink alcohol nor smoke cigarettes, only maryjane once or twice a day after work to calm the nerves. I talked to my mom and she said thyroid problems run in the family so I may get that checked out. Hope you guys and girls are all doing ok! Really hope this isn't something that's life threatening.

I don't know If you guys will respond but I'm 21 male I've suffered from what I was told is Anxiety an panic for 4 years but I've never woke up shivering an scared feeling like throwing up like I did today it was really scary my body was trembling an I started googling until I came upon this I felt a bit better i wish there was a way for all this panic to go away its annoying

ok folks, please have an open mind. I have experienced the same as you are describing...for the last 5 years or so, about an episode a year, maybe 2. I'm very spiritual, so besides researching physical cause, I also researched spiritual cause. What I discovered has convinced me...and having studied the subject for numerous years. If it rings true for you...research it yourself.

Uncontrollable shivering is a classic symptom of Ascension.

I've had this problem periodically since I was a child... the first time I remember it happening I was about 8 years old I think. Im now almost 30 and have learned a few things about the episodes. I've learned that if Im going to have one of these attacks I will begin feeling a little sick before going to bed. Generally I will think Im going to throw up and will go to bed early. However I've learned recently that if I go to bed and focus on relaxing every muscle in my body it will keep the "waking up shaking thing" from happening. Like several others have said... if I do have an episode where I wake up with the shaking the only way to stop it is focusing on relaxing my muscles. Typical response when you are shivering and want to stop is to tense up... this just makes the shaking worse in this case though. If the shaking continues and I dont remember to relax I beging feeling naseaous and will get really bad diareah... I assume because the muscles in my intestines are contracting too much. Luckily I have learned to notice when this is going to happen and have been able to control it before I go to sleep.

It's called "rigors" It may be described by patients as an attack of uncontrollable shaking. A history of rigors should raise suspicion of infection, particularly bacterial infection.

I really hope someone reads this and can help me. I am loosing my mind and want to know if something is wrong with my daughter. Please anyone if you can help, please respond.
I have a 9yr old daughter, who during most of her life has has a few health issues but theirs one that stands out and is driving our family and my poor child insane! At 3 months old we had to take her in because her eyes started moving rapidly from side to side and she started choking then caught her breath and cried. My mom stated it looked odd to call the doc, we did and the test began. Again at 6months the same thing, this time her little body tensed up, eyes side to side, caught her breath and cried. She stopped growing for a bit, was not in normal range. Time went on test after test and nothing. She kept having these symptoms. This is what is going on now, at any time of day- -her eyes all of a sudden get droopy, she feels real cold, her teeth start to chatter, she starts shaking bad, she get nauseated, she is kind of out of it, she is now saying she gets dizzy, before this happens, she knows when her 'episodes' are coming on, her body temp drops to 96.0 or lower she breaks into a sweat, pale clammy cold skin, but sweats. She's had this her whole life. This is our normal. She will have them daily. They will go away for a month or two then come right back. We have seen cardiologist, neurologist, endocrinologist, rheumatologist and sleep specialist, our next stop is a pulmonologist. Her primary doc says they think could be associated with sleep disorder. She is so tired all the time now she falls asleep in class. She crys all the time and has every type of blood test out their and other diagnostic, MRI, CT, ultrasound of heart, eeg, ekg, sleep study and nothing. She is so used to the lab she doesnt even cry anymore. All this she still in the GAte program for gifted and talented students. I am so proud of her. I need to know, we need to know what is wrong. I'm afraid if we wait for it to come out on its own like my family said so all the poking and proding can stop, that it will be worse if we wait. Anyone, please anyone. If you can help. Please advise and what you have found this to be or think this could be. Appreciate your kindness. And wish you all well.

This Just Happened To Me, I was Shaking Really Bad so i had thought i was just cold so i closed all my windows, however this did not work, So i did what my grandma would do
Fix me a cup of tea however i was nervous so it may be that which caused a panic attack
After Sipping the tea(chocolate) i felt fine witth no shivers, I will come and update

It Started at 3:20 ish and ended 4:13 ish, I think i felt more of a nervous feeling , one that i have felt before when something bad happens

I had this problem when I was younger (circa 15 years old). I completely ignored it, taking solice in as many warm blankets as I could find. It ultimately went away on its own accord, so I advise just waiting it out. You don't have an anxiety disorder based solely on this symptom. A panic attack may resemble a pattern of bodily arousal, but its defining characteristic is your malappraisal of its significance. Thus, as long as you trivialize this condition, it won't bear and psychological significance.

I had my first episode last night. It started by me feeling like had some body ache then I started to feel cold. The violent shivers began and the were bad almost painful and I couldn't get my hands and feet warm, felt weak and my head hurt. i had four blankets and comforter on before I started to get warm. When I woke this morning I was a sweaty mess.
Now I feel like I partied all night. What a feeling. Anyone figured out what's going on?

You know, I've had this attack for years, though usually mild, would start shivering as if I was hypothermic till I got into bed an warmed up, but last night was the worst ever. When I was almost asleep, my joints started to ache, just like i was getting the flu but it came on fast and it hurt.Then I started to get cold ( although when you think about it, it's still not the same as a normal chill ) I started to violently shake, like a seizure, my muscles tensed up, hard to breath, it kept happening in waves. After about a half hour of this I painfully got myself in the bath to warm up. soon as my body started to warm up I started throwing up. Got out of the bath and back into bed and for the rest of the night it was in between sweating and cold.

This is definitly not panick attacks, cause when I was in the bath I notice my legs were bluish purple a sign of poor circulation, my mother thinks it is either migraine related or raynaud's.

Has anyone else experienced seizure like shivers and stomache sickness

This happens to me every so often and I can say I'm 99% sure its GAD. Whenever it starts happening I pick up my guitar and start playing a difficult classical song that takes full concentration and it stops within 30 seconds flat. I used to have 5-10 panic attacks a day but with medication and therapy I have roughly one every other day. Though these bouts of shivering don't feel like a normal attack playing my guitar makes both go away in less than a minute so I really believe it's psychological

This happened to me last night, I'm so glad I'm not alone, though I wouldn't wish it on anyone. I was lying in bed, thinking I was a bit cold, when I start shaking uncontrollably. I wasn't that cold - it was maybe 20 degrees (C), but I felt colder than I've ever been in my life. I was shuddering so hard I could barely move, my teeth were chattering, my muscles were contracting, my hands were going numb. I thought I might die if I didn't get blankets, but getting out of bed was very hard, like willingly jumping into a frozen lake, and also physically difficult, like I weighed twice as much as normal. I staggered to the linen cupboard, almost doubled over, grabbed all the blankets I could and went back to bed. I knew I wasn't physically cold, so I tried to relax, and finally started to warm up, then went to sleep. I woke up later absolutely soaked in sweat (I had 6 or 8 blankets on me), and after that I couldn't sleep much, had lots of bad dreams and broken sleep. Today I'm physically sore, I feel like I've got the flu, vague nausea, dizziness, wooziness etc. Before I went to bed last night I had one of those brief violent shakes, like when people say a goose walked over their grave, but I didn't think anything of it.

I've been weaning myself off an antidepressant, and I've had very mild panic attacks before, but nothing like this. I really hope it won't happen again, but if it does I'd definitely consider calling an ambulance, it was awful.
