Hello, I am new to this site and I have a question about rectal bleeding with a colostomy. In November of 2011, I had surgery and had to have a colostomy. I have been doing fairly well but I have a problem with rectal bleeding off and on for about the last 4 months. This is bothering me and I wonder if anyone else has had this problem? I am waiting for a call back from my doctor, but I am wondering if I just haven't healed yet from surgery because of radiation damage or if there might be some other problem and this worries me! If anyone has had radiation and has had a colostomy with rectal bleeding, could you give me some ideas as to what to do? Waiting for my doctor to call.
