Colleen, Sorry if I gave the wrong impression. My intention was not to solicit amateur diagnoses, but to inquire if other people have experienced the same kind of long-term severe rectal pain that was dismissed as not resulting from colo-rectal disease. I have spent years in quality-of-life destructive pain with no attempt at a diagnosis from either a gastroenterology or neurology. The connection to radiation treatment for colon cancer is not a diagnosis but my own conjecture. Yes, I sought relief from this pain from a surgeon. That was an error. Thank you for your comment, Carleton
