I had a complete hysterectomy 20 years ago for a bad case of endometriosis. I have lately been having pain and discomfort in the lower abdominal area and my right side. I have heard that sometimes all of the endometriosis is not removed and it can come back later and attack other organs such as the bowel and bladder I went to my gastroenterologist, thinking it might be my ulcerative colitis acting up. She said since I had no blood or mucous, she didn't think it would be that. I also did not have a bladder infection. She suggested that I have a c-scan. Has anyone else had this problem ?
