YOU NEED TO SEE YOUR DR. not your favorite web board!!! This is in your blood not surface or skin. I too was afflicted with boils so I know whaere you are coming from. yep they hurt.
First you do not "pop" a boil.. you slowly bring it to a head with heat then open with steralized needle, use antibiotics, makeing sure you have all the hard core.. which is painful.
Second are you SURE it is a boil??? My husband has had some sort of puss sores coming up on his head under his hat too. the Skin specialist gives him medicine to put on it and he had a dose pack of steroids also. he has them in sections.. not one at a time.. the Specialist even doesnt know how to keep them from coming back..
See your DR!!! dont mess with it!!
