Hey there. So I've had these for a while and well now I wonder even more so what they are. Was thinking it was pearly papuil ( or whatever!) but from pictures I've seen they are smaller. Seems like mine is just a few patches of skin that are poppable but come back after a few days of wound. Please help as I can't figure out what it is. This is what it looks like.
