A boil is a painful, pus-filled bump under your skin â the result of a bacterial infection of one or more hair follicles. A carbuncle is a cluster of boils â painful, pus-filled bumps â that form a connected area of infection under the skin. Boils and carbuncles are painful, pus-filled bumps that form under your skin when bacteria infect and inflame one or more of your hair follicles. Boils (furuncles) usually start as red, tender lumps. The lumps quickly fill with pus, growing larger and more painful until they rupture and drain.
