I am having the same problem, it is so bad that I have pain in the rectum, perinium and down my legs. Nothing helps. I am bloated all the time and if I try having a bowel movement I strain until I bleed and if anything comes out it is so small. I finely did some reading on having a colonic. It was worth a try because I felt so bad, I called and she took me on an emergency basis, I told her I was terrified she assured me she would take really ggo care of me, I went and she was so wonderfull to me and so gentle. The procedure was so comforting to me and felt wonderful, I had an enormous evacuation with a lot mucous etc., my belly went down also. I go tomorrow for my third colonic, I can't explain it but I am so excited to have this done to me, it's a wonderful comforting feeling when the water starts entering my rectum and then to start passing all that feces. Please try it you won't regret it, you may experience a little cramping but it is well worth it in the end and it is nothing like what we both are going through.
Just lay back and enjoy it and get the relief you need.
God Bless you
