ok. so last night I had this really bad headache and it took me about 2 hours to fall asleep when I layed down. When I woke up, I was sweating...a lot. So I took the covers off of me. I was fine for about 20 minutes, then I started SHIVERING. Every time I put the cover back on, id sweat. everytime i took it off, I'd shiver. I felt really hot all day, but not like a fever. WHAT THE HELL IS WRONG??? im scared. i also feel reaaly dizzy when I get up from laying down for a long time, and I feel a sore throat coming on.
