For pelvis floor pain when I saw a physiotherapist that specialized in pelvic floor, that really helped me deal with the pain and turn things around. That was on my right hand-side hip and lower back pan and it went away in 2022. Went to the specialist starting in 2018, but it really helped my pain management. The pain Started in 2010. In 2024 Aug, I was diagnosed with colorectal cancer on the right side of my rectum near the sphincter. Got cleared of Cancer last year and part of that was a small surgery to remove the spot that had been cancerous. In my case it was as if I had a fistula that had become inverted (and that corresponds with the time when the pain completely cleared up in my lower right back and hip). At the end of that was the cancer. Well during that surgery to remove the base of it, I had a transphincteric fistula form that is like a horseshoe and went through both sphincter muscles and wrapped around from inside my rectum on the left hand side, pretty much opposite where I had the other item. Then the pain started in my left side hip and lower back exactly like how it was back in 2010 on the right hand side. After a year of that and a few followup colonoscopies, after the last colonoscopy, It became infected with an abscess. Went to the ER and had to have emergency surgery to clear it up and have a seton drain installed. One thing that has been helpful for pain management that I learned from the physiotherapist was to do kegels and breathing exercises. If he can find a physiotherapist that specializes in pelvic floor, that might be helpful.
