in the rectum or anus could be caused by a number of different things and each might require a different treatment so it would be very hard to generalize to try to give you some suggestions.
at the anus. I had a rectocele repaired. I was told i had an internal hemmorroid but that was not causing my problem. I am using hemroidal cream to see if it helps just in case i can shrink it and to help after the doc looked in there.
