A boil or skin abscess is an infection localized deep in the skin. In time, the boil hardens and becomes firm. The white blood cells will eventually soften the center of the abscess to create pus to eliminate the infection. When the pus forms a “head” it can be surgically opened or drained.
Types of Boils
Carbuncle or furuncle boils are skin abscesses caused by Staphylococcus aureus bacteria.
