[|Human|] I have a small lump that seems to leak puss just above my anus. It is painless but irritating as I know its there. I have been to the doctors twice about this back in November but they tell me it s just a blocked gland or duct. It doesn t seem to be going though. Can you help?
[|AI|]  Hi. A small lump, leaking pus, above anus is usually a fistula-in-ano unless proved otherwise. The best way to get a diagnosis is a digital and procto-scopy examination by a Surgeon. Confirmation is done by a histogram either by x-ray or MRI (if available) for its nature- whether this is high or low. The low fistula are easy to treat surgically. High types are a challenge even for a reputed Surgeon due to its anatomical difficulty. Please go for a proper diagnosis for a perfect plan for surgery.
