Hey everyone. It all started Monday when I ate dinner. I had a greesy food, and as soon as I ate it I got a stomach ache. It appeared in my upper abdomen. I had to go to the bathroom really bad, it helped alittle. Now today is wednesday and its just this plain discomfort in my upper abdomen and alittle on the left and right side. Its not painful just discomforting. A few months ago the doctor said I had viral gastroenteritis. Could the food I have ate upset it again? I am mostly going to go to the doctor. I am 16 years old, a male. Thanks for your help.
