I had my rectum removed last year due to rectal cancer,7 years before that I had a total colectomy due to FAP. Here lately I have been having really bad pressure, like I need to have a bowel movement bad,Its not always painful but it does happen when the urge to go is severe, Im not sure why I am all of a sudden having these, Is it maybe because I am backed up somehow? or do I have a partial blockage maybe? Whatever it is It is really aggravating me,I notice when I get nervous about something I feel the need to have a bowel movement.It is like my rectum is still very much there and something needs to come out, Please help me with this, I feel silly about this so i am embarrassed to call my doctor over this, thank you for any and all advice, becky
