yes I have had plenty being diabetic. get some ichthammol and put on it also hot baths as hot as you can stand it helps there are some old home remedies that work also but the ichthammol works better than anything i have ever used. and trust me I have had plenty of boils some the dr. had to give antibiotics for . just watch what you are doing cause staff can also make boil like abcesses come up. if it hasnt busted in a day or 2 you prob. should go see your dr. to be on the safe side.
