Is it normal to get sick again immadiately after getting well

I was sick all of last week then this week I have been fine and gone about my life preparing for easter and gone to meetings and stuff and I have not been tired or had any symptoms.
All of a sudden last night though I got sick in a second and my throat had been a bit sore all day but nothing bad I even had some wine and celebrated easter as usual then all of a sudden in the evening my entire body started to ache so badly it felt like someone had beaten me up, every single limb hurt like hell and felt sore and literally every part of my entire body i'm not even kidding... it was hellish. I was still feeling clear in my head though and not tired so I didnt go to bed but all of a sudden when im sitting talking to my mom and trying to ignore how sore I am I get chills and it wasnt cold the chill came from inside me. I started freezing so much it almost hurt inside and I was physically shaking yet I didnt have any fever.... very strange. Then my brain started "zapping" or spinning very quickly it felt like. Well I guess they were brain zaps.
When I went bed my entire body was freezing cold except my head, my head felt like it was on fire or like I was lying infront of a bonfire with my head right next to it and I couldnt sleep well all night because my body was in so much constant pain it even hurt in my sleep and I had the oddest dreams... In my dream the pain was visible and it looked like a bunch of vivid, crazy colors that were all around me and I couldnt escape the colors I was trapped inside of them and I was panicking because everything hurt so much and was so chaotic. I dont know if at that point I had a fever since it was at night. I still feel shaken from that. I have no appetite and my body feels weak but otherwise my symptoms are that of a normal cold, my throat is a little sore and I have a lot of mucus and I dont know why im sick again when I just got well. Does it seem like I should book an appointment with a docotor??
