I'm at a loss at what to do. For over a year i've been having some sharp pain around by belly button, along with gas and foul smelly, burning, and floating bowl movements. I've seen a gastroenterologist and had colonoscopy, endoscopy, small bowl series, an abdominal ultra sound, fecal tests, and alot of blood work. Any sort of infection has been ruled out as has celiac, crohn's, and ulcerative colitis. My doctor told me its just IBS and there is nothing she can do. However about ten years ago i was diagnosed with IBS and I know what foods to avoid, I'm lactose intolerant as well and i've going completely off milk and my symptoms don't change. I'm only 20 but i've always had some digestive issues so i know how to eat healthy but nothing i do works. I take hyoscyamine and it helps a little but i'm still having problems. My doctor has given up or just doesn't care so i'm someone has some suggestions that could help because i'm really at the end of my rope.
