hello, my boyfriend has been experiencing hard bumps on his scalp that are sometimes painfull.he has had them for over 3 years..and sometimes even pop like a pimple. he has experiened itching in the scalp also. he thought when he first got one that it was a spider bite because he found a spider under his bed. Recently we found a swollen lymph node right behind his ear that isnt painful at all. He sweats alot so it could be a oil and sweat buildup..when they pop he looses hair in that spot and then when it is all healed it grows back. Im not sure what it is or if its threating...i thought it could be ringworm but i feel like i would have gotten it by now by touching it.right?..please help me we cant go to a doctor he has no insurance.. any info would help!
