[|Human|] I have a small lump on the top of my butt crack. Its on both sides, reddish, and feels kind of raw. Kind of looks like a circle around the top of my crack, but I see it more when I spread my checks. At first it only hurt to sit backwards, like relaxing on a couch, but now it even hurts when I lay on my back or bend over (its been 2-3 days). Its kind of swollen & raw (feels hard). Doesnt hurt to touch it, walk, sit up right (unless the chair is weird), & doesnt itch or smell. Im wondering if its a rash & I should just buy diaper rash cream? But it doesnt look like a rash & doesnt itch. No change in detergents or lotions. Didnt bump it against anything either.
[|AI|]  Hi, It seems that there might be having some infection like dermatitis on the part due to poor local hygiene as it is difficult to reach for proper cleaning the part. There is more perspiration on the part leading to infection. Now it seems that there might be having bacterial infection giving this problem. Apply antibiotic cream after cleaning. Go for one antibiotic medicine course for 3 days. Keep local part perspiration less and clean and take care.
