what do you do about a new abscess
By "hurting jar", do you mean hurting JAW? Like the abscess is in your mouth near or on your jaw? Because that's different than one on your skin. An abscess in the mouth can be very dangerous to your health. I don't want to dispense too much medical advice... but for now, I'll say if its in your mouth, don't bother it too much. You don't want to make it worse by irritating it or rupture it or who knows what. Not in your mouth or on your jaw. Those things carry hazardous materials.
I'm getting myself all worried for you now. Can you clarify the location of the abscess? I read up on this just recently and have some literature on it that may help.
