Hi there. last night i had a fever, felt weak for most of the day. i also had to make a few trips to the bathroom due to an upset stomach. today my stomach is better but my neck is really stiff. feeling weak as well?

Virus: In view of the associated fever this is most likely a viral intestinal tract infection (as opposed to food poisoning) and usually runs its course in several days. Rest, drink adequate fluids, avoid roughage, greasy foods and milk products if you're experiencing diarrhea. Soft solid foods are best. Tylenol as needed for aches,pains and fever. If diarrhea is problematic take kaopectate as needed.
