shower's and more shower's. 2x a day will keep the bumps away..
Hello,
Boils are caused by infection of the hair follicle by staph aureus. Hair follicles that are blocked by greasy creams, petroleum jelly, or similar products are more vulnerable to infection. They do not persist for so long like months or years as they spintaneusly rupture. What you seem to be having for such a long time is sebaceous cysts. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.
Generally no treatment is required but they become painful then it means they are infected, then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required. Then consultation of a dermatologist is required.
I hope that helps. Take care and regards.
