As long as the boil isn't on my face or neck or some place where a scar will be seen. I don't care if there is a scar! The bottle method will pull the core of the boil out, it works! The boil will not come back!
Glass Bottle Suction Technique

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.
