I have pain under my rib on the right side. I've read many saying IBS. I have IBD, the exact IBD being Ulcertive Colitis. I am not having a flair up, but I have a pain under my rib. I first thought liver? I don't think that is what it is. The pain is bad. My bra hits it and makes it worse. My stomach is REALLY bloated! I am not exaggerating when I say I look very pregnant. Any thoughts or insights would be greatly appreciated!
