A word to the wise... if you are told by a doctor that you have radiation induced proctitis, tell the doctor that under no circumstances should it be "cauterized". I had that done and have been in misery ever since. I had a colonoscopy in December and have been in pain since then. I am scheduled to have a sigmoidoscopy for the second time in search of an answer... by another doctor of course. I am posting this in hopes that it may prevent anyone else to go through this hell. If you do have a case of radiation induced proctitis, there are other less invasive treatments to try... but cauterization shouldn't be on that list.
