I know the rectum stores feces, but what is inside of the perineum? I feel a lump there, it cannot be seen with a mirror, it is inside. When I have a bowel movement, I feel that I am incomplete. I am unsure if its the lump that is in the perineum that is stopping me; I don't know if it is stool. I had a digital rectal exam in August, because I told the doctor I felt a blockage in my anus, but the doctor said everything was fine. However, this was before I noticed the lump in my perineum. I did not have the perineum issue, only the blockage I felt in my anus. Could she have missed something?
