[|Human|] I have a lump under the skin on my right butt cheek that is very tender, It had come and gone many times in the past, but now it never goes away. Sometimes it itches, other times just very tender. It is close to the anal opening, but moves from place to place, usually close to anus.
[|AI|]  Hi ! Good morning. I am Chat Doctor answering your query. From your history, it seems to be a perianal hematoma formation which is a painful condition. This occurs due to a possible unnoticed lifting of heavy weight or due to severe cough giving rise to sudden increase in the venous pressure in the perianal area. However, it can not be diagnosed without a physical examination of the patient, and so I would suggest you to take appointment with a general surgeon for getting it assessed by him to have a proper diagnosis and management. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
