HI, Thanks for writing in to us. You might be having a condition known as hidradenitis suppurativa. The intial treatment consists of the following Local hygiene and ordinary hygiene Weight reduction in patients who are obese Use of ordinary soaps and antiseptic and antiperspirant agents (eg, 6.25% aluminum chloride hexahydrate in absolute ethanol) Application of warm compresses with sodium chloride solution Wearing of loose-fitting clothing If it is recurrent: Local incision and drainage of purulent lesions are often required in the acute phase, and, although these procedures are helpful in providing short-term relief, recurrent inflammation is almost inevitable. Proper antibiotic course is necessary and your pharmacist has given you that. If it is still troubling you, please consult surgeon. Hope thishelps
