Nausea, cold sore, headache, stomach and chest pain. what's wrong with me? i've lost my appetite and just don't feel well at all.

Cold sore: It sounds like you have something viral. You need to keep fluids going, alternate tylenol (acetaminophen) and motrin. And treat the cold sore.

Uncertain but this: Could be viral in origin. Consider rest, hydration with water, ginger ale or ginger tea for nausea/ GI upset & tylenol (acetaminophen) for pain. See dr. For severe abdominal pain or temp of > 104. Hope you feel better soon.
