i have this extremely small group of tiny bumps on the skin that comes down the back of the head. i was given a hand job a while back and the skind actulally tore slightly. for a while there was a small cyst or whatever from where it was healing. over the past two months i have been noticing that it's size is bigger and it now has the small tiny tiny patch of bumps, they look kind of pinkish white. an example is maybe a small small patch of egg type looking things. i actually pulled one out. it never itches or anything. have no idea what it is. any help?
