I have a lump on the outside of my anus. It feels like a swelling under the skin. It is not the color of hemoriod. It is skin color. It seems to shrink like at night.I would say it is the size of a marble. Doesnt really hurt.
Unfortunately, it is not possible to make a specific diagnosis over the internet.
Most such lesions are entirely benign, but you should still have your personal physician look at this lump. If he/she is concerned about the appearance of this lesion, then it can be excised by a surgeon and sent to a pathologist for review.
