So after reading all of this, it sounds like you may have what I have. My inter Sphincter muscle is the problem. I have finally found out why I have so much pain internally. And I finally found someone who is helping me with the pelvic floor inter sphincter muscle. Sadly not many GI Drs look into this. But as someone put on this site we normally tighten down there about right after surgery so we did have accidents. My muscle is so tight she was shocked. And it hurt so bad having her check it. She explained that the muscle won’t relax and stays squeezed 24/7 and is surprised I can even go to the bathroom. So for starts I have to change my diet. And I have exercises for the outside core of my muscles down there. She said I was so weak. Usually after doing all these exercises my muscle might go right into where it needs to be. It’s like the inside muscles are doing what the outside muscles are suppose to be doing. (Butt, check, stomach and abdomen muscles). I was so shocked when she explained it all. It made so much since. And I had my first surgery 10 years ago yesterday. So for years I have been tightening that internal sphincter muscle.
I am her to help if you want to send me a pm. I’m slowly going to get better. And I am so grateful I have found someone who can explain all this pain. And it all makes since. I don’t think the GI Drs think about our pelvic floor muscles at all. I truly think that is part of your problem. She did give me an exercise to do on the bathroom while trying to go. I can tell you in a pm. Hard to explain it all on here.
I truly hope this helps you out. Also your OB/GYN might really be a lot of help with this matter. She would no best about the muscles down there. Good Luck.
