Pustules are usually caused by bacterial infection of the soft tissue of the skin: 1. If the area of the pustule is relatively small and has not yet broken, it can be treated with local application of antibiotic ointment, such as Bactrim, fusidic acid cream, compound polymyxin B ointment, erythromycin ointment, etc. 2. If the abscess is large and has broken down, it is necessary to go to the hospital dermatological surgery or general surgery in time and do the surgical treatment of drainage after local disinfection.
