Is it normal that i sometimes get suddenly dizzy for no reason?
Often, when I get out of the shower, or even if I just stand up, I think a rush of blood goes to my head or something. I get really dizzy for a few seconds, like 5 seconds, and I can't see and my eyes feel funny, and I feel faint. I also have a throobbing sensation in my head. Then, after a few seconds it goes away. Is this normal?
