The last day or so I've had some diarrhea along with mild vomiting. That lasted for about a day. And now today I'm still slightly nauseous. But along with that I have been getting bad pains and muscle soreness. Mostly in my upper body. Pains in my lower abdomen, along with pains in upper and lower back and along my sides. And with this is severe muscle soreness. It feels like the first workout after not working out for a while.

I've never had the flu before and I'm away at college - is this what it could be?
