What Is Wrong With Me?

Hello all -

well lets just start.

Last summer, about a month before I had to go away to school, one night I just got very ill. I threw up all night and all the next day. I went to the doctors and they thought it was just some food poisning. This got worse so I went to a gastrologist(spelling?) and he thought it was just acid reflux and stomach spasm. So he prescribed prilosec. It seemed to get better. Then the day I moved into college(im a sophmore) the first night I felt very sick so I went into the walk in clinic. They prescribed me prilosec and they also told me to take "gas-x" or the clones with the same active ingredients, after each meal. This I think made me feel the best, however I was still never fully feeling well.

A week before thanksgiving, I got very ill and began throwing up all night, went to the hospital and they said I had stomach virus from some food.

So now I came home for x-mas break, and I feel like im getting ill again. The pains are in my lower abdomen. Left side under rib cage is where it hurts the most, its like a constant pain. I feel very uneasy around eating and just being active. I went to the gastrologist, and he prescribed me dycolomin(spelling?) but he determined it was irrital bowl syndrome. But he had some doubts because my bowls have been fine, been solid every day 1 time atleast. So 3-4days into it, I got really sick again, very uneasy. I went to the gastro again, and now im scheduled for monday for a upper gi scope.

Im just curious, what is wrong with me? I'm so fustrated.

I have been looking at post here, and some have said stress and anxiety. Im just not sure, I was very stressed out in school, but I wasn't feeling like this during the school year.

Last summer I had the ulcer test and it came back negative.

Any insight guys?

Thanks,
dan
