I have a cyst/boil/round painful something that keeps popping up on my very inner labia. It's like the size of a marble, it comes and goes and it changes sides. I've never popped it or anything it's just there for a few days and then the next thing you know it's not. It huuuuurts and if my lips get shifted or tucked weirdly after I wipe or move or whatever it's like searing pain. Anyone ever experience this? It happens like once a month or every other and doesn't seem to be affected by my cycle. Please help!!! I'll post a picture if needed but it'd be p graphic. Lol
