I have been constipated for a long time. I use laxatives and enamas due to small hard BM and does not work well. I have mid upper ABD pain that was just occ but now is constant, the pain is so bad that I can not stand streight. After using an enama and passing small hard stool, I had the urge to go back to the bathroom and passed gas and something that looked like tissue came out from my rectum. Part of the translusant tissue had brown on it. I know this was not mucus because I have has mucus before on and around the stool. The tissue looked like something tore apart from the inside of my colon. I don't want to panic and run to the Dr. but I am very concerened. I also have abd bloating, pain and distention.
