I have a flat white, seems to be hard bump(?) just under the skin of my libia majora, it s closer to the clit, a little smaller then half the size of a pea. There is only one, it itches slightly but if I poke or pick gently at it with my nail (that s how i found out it was hard) it hurts. It honestly feels like it s connected to a nerv... what should i do?
