I'm sick right now, the whole coughing, sneezing, nausea bit. But the worst part in my stomach. Right now every time I cough, sneeze or even breathe, my stomach gets the most unimaginable pain in it, mostly on the right side. I can only eat toast, I'm really warm, which is strange because I am very cold sensitive. No one else I know has these same symptoms. What could it be?
