Hello, on my bikinki line groin area I get nickle sized bumps under my skin. I do shave and I'm wondering if it is ingrown hair, etc. Its normally just one. Doesn't hurt but if I try to bust it only blood comes out. No white head etc. I thought it was because of ingrown hair but I try tweezing all the hair out in and around it and nothing. Usually if I do that then a discharge will come out and swelling will down and by next day gone. But this one there is no head and removing the hairs does nothin! Help please
