Hiya Yayamei, I read your post and it sounds like you are having the same problems I had, after years of having toilet problems, my fantastic New surgeon discovered I had a prolapsed bowel. I had an operation called a Rectocele ( I don't think that's the correct spelling!!) but like you had to manually evacuate my bowel and it is not pleasant at all. I won't go into the details of the op, google it!! But I was told it was the worse case he had ever seen. After my surgery I was uncomfortable but not in agony. For me solving one problem created another and I had to have an Ileostomy a year later as my bowel had became totally incontinent. I really hope you get sorted out, if I can answer anything else just ask.
