I wanted to ask a question. About 2 days ago I figured out that on my anus, I have bump (small as 1-2 mm) which was not been there before. I don't know if it's a anal pimple, abscess, hemorrhoids. It is stiff with skin color but it hasn't pain on its own, but when I touch it, it's a bit painful. I'm not sure if it's a serious thing and needs more assessment?
