I have this bump under my lips in between my vagina and it swells up and hurts when I sit or walk some times and it dosent get very big just like a bump that you can touch and you dont pop it that I know of it's really weird to me and I dont know the cause of it I had it be for and it hasnt came for months and for some reason I have it again. Can any one tell me what it could be or if they have expirenced any thing like that be for???
