I noticed a pimple on my anus yesterday. Surprisingly it does not hurt at all when I have a bowel movement, but it's uncomfortble when sitting. There is no unbearable pain but there is a very mild persistent pain. Sometimes, when wiping, I tend to clean excessively. Do I need a doctor to look at it or will it go away by itself?
I don't think it's hemorrhoid. Everyone of us has that pillow-like cluster in our rectum.
