You should really get it checked out by a dr. You could be getting more boils. My husband suffered from boils caused by a staph infection which can be really contagious and spread if you are not careful about keeping everything clean. Wash everything in hot water and toss away everything you use to clean the boil with. Clean your skin with an antibacterial soap. Do a search on the internet on boils - there is a lot of useful information out there.
Good luck.
