It is possible for a few boils to go away slowly without becoming suppurative, and in most cases patients can improve their condition with aggressive treatment. A boil is an acute suppurative lesion localized to a hair follicle caused by infection of a single hair follicle and its surrounding tissue by a pathogenic bacterium such as Staphylococcus aureus. In most cases, non-purulent boils can recover on their own within a certain period of time, without intervening treatments etc. However, if the boil is red, swollen, hot, painful and hard, the patient can use topical medications such as ichthyolite ointment and mupirocin ointment for topical treatment, as well as oral antibiotics such as amoxicillin and cephalexin for anti-infective treatment. Early patients can also use far-infrared rays, ultra-short-wave irradiation and other ways of physical therapy, to promote the decline of inflammation. It is recommended that patients strictly follow the doctor’s instructions, actively cooperate with the doctor’s treatment, pay attention to personal hygiene in life, keep the affected area of the skin clean, dry, regular review.
