Patient: Good evening. Recently i i noticed a mark on my buttocks. I thought it was pimple so i tried popping it, and it didn’t pop. It Felt like it broke inside the skin. a day later it got worse. its literally right where i sit so everytime i sit down i feel like im making it worse. Its tge size of a golf ball and feels like a bruise. The head of it is like a blood blister.
