Re: internal perineum pain - post-op sigmoid colon resection
A lot of pain issues revolve around the pelvic region. I had pain issues after a pelvic surgery that never got better until I went to a special physical therapist for pelvic floor dysfunction. I cannot remember all the terms my PT used with me about the pain in the pelvic region. I know that I had a "short pelvic floor". All the pain from my pelvic surgery made my muscles down there all tighten up. Just like most tense/tight muscles, it caused me pain.
I did a bunch of research online to find the cause of my pain and a solution for getting rid of it. Many doctors just want to give you some medicine and say that you will feel all better in a short amount of time. That is not always the case.
While doing my research on pelvic pain and pelvic symtoms, some of the terms I came across were as follows: "Pelvic Floor Dysfunction", "Trigger Point Therapy", "pudendal neuralgia", "short pelvic floor", "Musculoskeletal Causes of Pelvic Pain", "vulvodynia", and "vestibulitis." These are just a few of the terms that I have read about regarding pelvic pain. There are many, many more. I know that burning in the areas you mentioned were involved with some of these.
Just do some research. I hope you can find some specific answers.
