Hi,
How are you? A boil, also referred to as a skin
abscess, is a localized infection deep in the skin. It starts as a reddened, tender area that becomes firm and hard. Eventually, the center of the abscess softens and becomes filled with pus. There are several different types of boils depending on the location: furuncle, carbuncle, cystic acne, hidradenitis suppurativa, or pilonidal cyst.
