Hello, Thanks for the query. Your symptom of painful swelling and cottage cheese discharge suggests a boil or furuncle which is infected. Staphylococcus aureus bacteria cause skin boils, also called furuncles. Boils, which form in a hair follicle and the surrounding tissue, start as a red tender lump that enlarges and develops a white or yellow pus-filled center. I suggest you to take antibiotics for 7 days. You can generally treat small boils at home by applying warm compresses to relieve pain and promote natural drainage. There is nothing to worry. Hope this helps. regards, Dr Nilofer
