Skin boils are inflammation caused by bacterial infection in and around the deep hair follicles. The main thing is to apply topical ointments with antibacterial effect, commonly used ones such as fusidic acid cream, mupirocin ointment, compound polymyxin B cream, and ofloxacin gel have good antibacterial infection effect, and the redness and swelling will subside significantly or even be absorbed in about 7-10 days after topical application. If the boil is more generalized, it can also be combined with oral antibiotics, such as cephalosporin. In some patients, localized boils with deep pus formation can be treated with incision and drainage in the hospital, and recovery is faster after the necrotic material is discharged.
