Hi Pepsi, Well it certainly sounds like IBS to me, considering I have been diagnosed with IBS and experience all those symptoms and more. The change in stool is normal for this disorder from all I have read. At the onset of my ibs, that was the first noticeable difference. Suddenly, after years of normal bowel movements, I started having nothing but miniature soft stool and occasional watery diarrhea. I also have gurgling,bloating and discomfort. I wouldn"t call it pain, although I have a very high threshhold for pain so maybe for some it would be considered as such. I wouldn"t worry about it too much since you"ve had the colonoscopy, it sure sounds like IBS. I had that done and also had some small benign polyps removed. As far as the gas goes, considering you feel it under your rib cage like I often do,(mine thumps sometimes) it is most likely just trapped gas according to my GI. Hope this helps, Good Luck
