kindly send picture of affected area for accurate diagnosis.

I think the condition is Hidradenitis suppurativa from the description provided. A proper assessment to determine the severity of Hidradenitis suppurativa is needed. It can be confused with some common skin conditions like boils or acne and hence a diagnosis is importane. Treatment is based on severity score and can be decided during a consultation. Most of the patients do well if they stick to the recommendations. Kindly see a dermatologist for a treatment plan. Further authentic information can be obtained from the link below
