Boil: Introduction. A boil is a large infection of a hair follicle, the tiny opening in the skin from which a hair grows. Boils are due to an invasion of bacteria that enter the follicle and cause a bacterial infection of the follicle and nearby skin. Boils are also called skin abscesses or furuncles.
This period depends on couples of risk factors, such as: 1  The main trigger causing boils. 2  The treatments used or medications taken for promoting healing. 3  The location of affected skin. 4  The severity of boils. 5  The presence of infection.
