I was at work yesterday and all of the sudden, I could barely stand up. I work in a restaraunt and had to lean on the counters to keep from falling down. I went home and layed in bed, under 6 layers (clothes and 2 blankets) and felt like I was outside. At 2 am, I had to rush to the bathroom and vommitted. I've had a fever all day, now go from being freezing, to burning up yet still feel freezing and teeth clatter. My entire body is in pain, I can barely stand up alone and move very slowly when I do. I have a migraine that hasnt gone away and it hurts when I bend my joints (mostly in my knees). I had back pain for the past 2 weeks that also has not gone away. The nurse said to take tylenol and drink many fluids which is what I've been doing, but hasn't helped much. Anyone have any idea what this might be? I'm making a doctor appointment tomorrow if I don't feel any better which I'm betting on.
