my husband has had what looked like an ingrown hair at first on his left hip bone for sometime now? he used to where a tool belt so i thought that was irritating the area so we did pull a few hairs to see if that would help a while back event tried to pop it. Now it looks really puffy some purplish color and bigger like he was bit by a spider and maybe filling with puss. but its not he cut it a bit nothing at all.its been there for at least 3 months if not more and he s starting to get pains down his legs and in his lower stomach. . and is painful to the touch now also?
