Hi doctor, I have periodic blood issue in my stool. It comes in very very little amount after every 15 20 days gap 2 months back, I realized that anus outer area is bit swell. But I ignored it with time yesterday, when I was checking anus area for same swelling, I saw red color part inside anus when I opened anus I am worried. About this red part. There is no pain at all attaching image. Please suggest what is this red one. Is this something serious? This is only visible when I force and open the anus forcefully.
