[|Human|] Im an 18 year old female of average height and weight (around 5 foot 4 and fits a UK size 8-10). I have no serious medical history. I recently had sex and noticed a large ball-like lump on my anus afterwards, which went down after a few days, leaving some excess skin, which seems to grow back to a lump when I need to empty my bowels... Im really confused about this as it soon becomes excess skin again, and is completely painless. Im just wondering whats caused it and if theres any way of getting rid of it?
[|AI|]  Hi, Dear,thanks for the query. Some more info is needed before cause could be told-as after the natural sex there is no reason-to get the anal lump. However, the lump which is there might be old -anal problem-mostly old anal fissure with a tag covering it ./or could be sentinel pile indicating its chronic presence. It needs simple excision of the sentinel pile under local. If its with anal fissure-which any surgeon could tell you, then-Anal Stretching under anesthesia. Thnks again. Wellcome again. Hope you are satisfied with the answer.
