What is wrong with me?

ok so ive had scarlet fever, and my rash is going, and my sore throat is gone, so has most of the yucky white stuff that was on them, but i woke up 2 days ago, and ever since then i have felt so werid. I cant explain it, its like ' im not really here, and im in a dream ', i feel kinda numb and tingly, and when i move around it feels weird, and all i wanna do is lie down with my eyes shut, Im kinda better today, but i have a bad headache that really hurts when i sit up quiclky and cough etc. One time, I couldnt close my mouth it was just kind of open and I had a spaced out look on my face while I tried to watch t.v. The way i feel is very strange so another way describing it would be, fuzzy head. Just talking and expecially undressing and walking was hard for me. Because my legs felt like jello. I felt like I was half in a dream state, because my whole body was aching and fuzzy. help x
