Carbuncles that persist longer than 2 weeks, recur, are located on the spine or the middle of the face, or that are accompanied by fever or other symptoms require treatment by a health care provider because of the risk of complications from the spread of infection. Warm moist compresses encourage carbuncles to drain, which speeds healing. Gently soak the area with a warm, moist cloth several times each day. Never squeeze a boil or attempt to lance it at home because this can spread the infection and make it worse. Deep or large lesions may need to be drained surgically by the health care provider.
Meticulous hygiene is vital to prevent the spread of infection.
Draining lesions should be cleaned frequently. The hands should be washed thoroughly after touching a boil. Do not re-use or share washcloths or towels. Dressings should be changed frequently and discarded in a manner that contains the drainage, such as by placing them in a bag that can be closed tightly before discarding. Carbunculosis may heal spontaneously and usually responds well to treatment.
