Hi I have burning in the rectal area. I have IBS with constipation. I had 2 colonoscopies within 3 years from 2017-2019 and all good. I was having a uncomfortable pressure gas sensation on my left side above my colon for a long time. That’s why he did the colonoscopies . Then I first experienced burning in 2022 after running a 5K. Lasted 2.5 months. Went to Gastro and Urogynocologist for internal exams and no issues found. The urologist said it might be a perennial body or sphincter nerve issue, which is a pelvic floor issue. If the muscles are not relaxing in your pelvic floor, they can press up against nerves which can cause a burning sensation . I went to a physical therapist since I also had a nerve issue/pain in my buttocks area from the run which I thought is the reason why I had the burning in my rectal area and after one session of PT and doing some exercises at home that nerve pain went away and then a few days after that, the burning sensation in my rectal area went away as well. In January 2023 I decided to do a two hour walk with 10 pound hand weights and a few days after that, I experienced really bad burning sensation again. I went back to the Urogynecologist and another internal exam revealed nothing that he can feel.
I have a appointment scheduled for the Gastro doctor at the end of the month and I have a physical therapist appointment scheduled for next week. I have no clue if the physical therapy may help again for a possible pelvic floor/burning issue. I have very small hemorrhoids. I had very, very large hemorrhoids removed many years ago. It was a very painful surgery. I only feel relief when I lay down. When I wake up in the morning, the burning is not as bad but as the day progresses, it gets worse. It makes me feel like I have to have a bowel movement or urinate and I really don’t so it may definitely be nerve related. I know how frustrating it can be when you don’t feel well, and no one can give you an answer.
