My son is 27. 3 days ago started noticing a bump on top of head with pain to touch. No trauma. Now there are two additional lumps one behind ear and one in front of ear. I have tried hot compresses on the head thinking an infected hair or boil but now I am not sure. No fever, no other symptoms expect the sensitivity to touch.Of course he has no medical insurance as he is unemployed but if there is concern I will seek medical attention for him.
