Damage to the hair follicle allows the bacteria to enter deeper into the tissues of the hair follicle and the subcutaneous tissue. Furuncles may occur in the hair follicles anywhere on the body, but they are most common on the face, neck, armpit, buttocks, and thighs. Furuncles are generally caused by Staphylococcus aureus but may be caused by other bacteria or fungi. A furuncle may drain spontaneously, producing pus. More often the individual, a parent, or a physician opens them.
Furuncles can be single or multiple.
Some people have recurrent bouts with abscesses and little success at preventing them. Furuncles can be very painful if they occur in areas like the ear canal or nose. A health care provider should treat furuncles by the nose. Furuncles that develop close together may expand and join together, a condition called carbunculosis .
