I have a six y/o little brother who has gotten a cyst or boil on his face, or something else.I cannot tell. It s red and pus filled, the size of a bb gun pellet, and doesn t seem to cause him any pain, he hardly notices it. He s had it on his face for a week and a half, it just literally popped up. My question is if anyone could help me identify it? Then hopefully proceed with the removal of the unsightly blemish.
