Hello Lonie!
You are probably at your GI by now but my experience with the naval pain was one of two things... first, I had acid reflux which was irritated and causing me pain, secondly when they did my last colonoscopy, they found irritation in my small bowel which was uc related. It could be one of the two - I have begun taking over the counter prilosec which has helped with these symptoms. Good luck and let us know what they tell you!
