I work for a GI physician. I would definitely say to get this checked as it could be a number of things. Probably not much, but it is better to be safe than sorry in this area of medicine. I will say this, when I had exams I could not eat as I would immediately have to run to the bathroom. While I was driving to school, eating or not, i would get the same symptoms. I have/had ulcerative colitis, which they say you can never get rid of. I am not sure if what I had was ulcerative colitis, except I did get a colonoscopy. I just wonder if stress can cause a mimick of a disease. After it was brought under control 6 years ago, I have never had another symptom and do not take medication. Even my doctor is flabbergasted. Hope this helps.
