Hello,
Without examination,confirmation of a diagnosis is tough, but it sounds like folliculitis or
boils.
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.
Please keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove. Avoid any kind of cosmetics.
