What are Boils?
A boil is a skin infection that starts in a hair follicle or oil gland. At first, the skin turns red in the area of the infection and a tender lump develops. After four to seven days, the lump starts turning white as pus collects under the skin. If the infection spreads to the deeper tissues of the skin, then it becomes an abscess. The most common places for boil's to appear are on the face, neck, armpits, shoulders, and buttocks. When one forms on the eyelid, it is called a sty. If several boils appear in a group, the condition is more of a serious type infection called a carbuncle. Before boils can heal completely, they must open and drain. Boils typically resolve on their own within two weeks of onset.
