Inflammation / boils in inner thigh.

I keep getting inflammatory boils on my face, near my ear lobes at least twice a year & subsides automatically without medication. In the past 2 years, I started getting such inflammation in my inner thigh which becomes very messy after few days. Initially it started subsiding automatically but last time it was horribly severe and had to visit a doctor who diagnosed it as Hair follicular infection but since the root is deep it had to be operated. I underwent a minor surgery to get it removed. When I asked the doctor about prevention, he mentioned that it's a just fate. After that once when such a boil came 6 months before, I googled and tried some home remedies by applying Turmeric paste, Onion slice bandage. It disappeared. A similar boil occurred again last week and now I am worried. these boils are not at the same place always but it's in the same surrounding. Want to know how to cure it and prevent it. Someone suggested SAFI.. Will that help. Pls advice. I don't want 1 more surgery
