So yesterday I found this little grayish spot on my inner labia and it hurt a little bit but it didn't worry me. The next day it hurt very bad. It is a large lump about the size of a penny and it's raised off my skin. The top of it is blackish and sort of looks like a scab. There are other smaller dots around it too. I'm 15, have not had sex, and have not shaved down there in a long time. I don't know what could have caused this but I don't know what to do. Advice??
