[|Human|] My husband noticed a lump inside his left butt cheek. He had this a couple years ago, however it was closer to the anus. We had it checked and they did not find anything in his rectum or colon. Now he has finds it is getting bigger, and when he sits it hurts. it is still inside his cheek.
[|AI|]  Hi. Thanks for your query. Read the history about your husband and understood the problem. The most probable diagnosis of such a lump inside the butt cheek which has recurred after a few years can be:Colonial sinus or a Fistula in ANO. The best way to get this confirmed is :Get examined by a General Surgeon. MRI helps the best to differentiate between the two. Another possibility can just be a boil. Any of the diagnosis, the best way is to get properly investigated and get operated.
