I've had this issue for about 4 months now. It's on the outer parts, around the labia. It swells up each month and fills with puss and blood. After it pops on its own, there remains a lump under my skin but deeper, so it can't really pop. I have no idea what this is. I haven't changed any of the products I use, I never cut myself there with a razor or anything. I have no idea where this came from and it just won't disappear.
