You may be suffering from folliculitis. It is an infection of the hair root. If it keeps happening repeatedly you may need investigations like Blood
sugar levels, blood counts, hemoglobin, ESR,
HIV, HBsAg and culture from the pus from the boils. A dermatologist will be better equipped to treat you and rule out underlying problems if any. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore
