I have been having gas pains for about 2 weeks. Not severe but I feel like there is water in my rectum. Then I have to go to the bathroom and get ribbon like stool, and a lot of gas in which when I am on the pot (sorry to go into detail) I pass gas and it feels like somethings coming out but isn't. I've had bad stomach cramps since 6th grade and have even passed out from them. I got a colonoscopy and upper GI which revealed nothing. They took a biopsy and it came back unremarkable, I had a stomach scan, and also ultra sound in which they just found a small polyp on my gallbladder but said it was fine. What is the deal. ANy help out there please?
