I have had so many tests, cat scan, lower bowel,endoscopy,colonoscopy. I have not found anyone else with my symptoms. I feel like there is a rubber band around me just under the sternum. If I wear a shirt that fits(not skin tight but just touches my skin)it makes it even more ponouced.It feels like your skin is stretched & you can't take a good breath.It is not actually painful, but it is very aggrevating,& tiring on your body.I have been trying for a yr. now to figure this out, they did take my gallbladder out last August but that didn't helpeither. I do have irriable bowel ,but this is not the same.Someone please help!
