one day i just notice there was a pimple or atleast i tought it was, under my chin and on the side of my head under my hair. well didn't think nothing of it. well its been 6 months now and they not going away. they really do look like pimples but i cant squeeze em and they are hard too. there isn't any puss or anything. i have no clue wat this could be. i'm 27 and i don't live the healthiest way. over weight too. i don't know if this helps.
