Have any of you ever gotten an ingrown hair on your labia? I've had them on my bikini line and pubic bone but never my labia. 
Anyway, I was taking a shower and, while washing, I felt a sort of know on my labia, like the size of a marble. I didn't realize it was there before and now I can feel it when I walk and it hurts. The size seems kind of big to be an ingrown hair so idk what to think. I can't see my OB until this afternoon (if he's even available) because of have my son and no car. 
So, I guess what I'm asking in addition to my first question is; if you have had one on your labia was it marble size or do you think it could be something else?
