So, I have a skin tag on anus, and near it a lump. And in the same place (maybe almost) there is an another small lump inside. Both cause pain while pressing and too much itchiness. I thought, it is an abscess and took medicines under doctor's advice but it doesn't work. They are not growing from many years and they never cause any discharge. If I consider, that the inside one is an abscess and external one is fistula. Why it never causes discharge? Definitely not pus or anything. I am on no treatment from 5 years. If they are piles, why they're not growing or causing thrombosis. Because I never feel they're disturbing my life. Please help, if it is an case of abscess and fistula. Is it really possible that an untreated fistula cause no discharge from years? Could it be associated to the skin tag? Are those lumps/bumps are part of it. But it causes itching by touch, pain and sharp pains sometimes.
