Also known as skin abscesses, boils form as a result of a cut or break in the skin, which leads to a bacterial infection. They are characterized as a red, tender area with a painful, pus-filled center that can open spontaneously or by surgical incision. Some boils are caused by an ingrown hair. Others are caused by plugged-up sweat glands, such as some types of cystic acne. Anyone can get a boil. They grow quickly and are usually painful until they drain. However, left alone a boil will naturally come to a head and burst open, allowing the pus to drain and the skin to heal. People with weakened immune systems are more susceptible to boils than the general population.
