When my husband was younger, he got several boils and carbuncles over the course of a year. The hospital lanced them each time and they usually came back. He also got antibiotics and perhaps other drugs. The worst one was a carbuncle, an infected boil with several heads. Finally his father suggested an old remedy and the doctor agreed to try it.
Find a bottle with a mouth just large enough to fit over the boil. Fill the bottle with very hot water. In a minute or two, dump out the water. Place the hot bottle over the boil and a suction will form, pulling out the "gunk". In my husband's case, the boil never came back.
