I have a small bean on the lower side of my rectum. I'm concerned. At night when I shower, it's there. I can feel it move. I don't know what it might be. It's dry and itchy. Should I be concerned?
Please go see a Gastroenterologist.
Yes. Go get it checked out. See a rectal surgeon.
You should have it checked out. It is a result of a viral infection or a clot in the blood vessel in the surface tissue. It might require therapy.
It might be a hemorrhoid. You need to have an examination to make a proper diagnosis of this lump.
