Boil pus plugs may or may not come out on their own. If a bacterial infection occurs in a single hair follicle, which is called a boil, the local area will be red, swollen and painful, and there is a possibility of abscess formation. ① When the tension of the abscess reaches a certain level, there is relatively little pus, the abscess will burst and the pus plugs will be able to be discharged; ② If the tension of the abscess is relatively small and there is relatively little pus, the abscess will not burst and the pus plugs will not be able to be discharged. After the occurrence of boils, it is recommended to go to the hospital, and anti-infective treatment is needed, such as the use of anti-infective ointment under the guidance of the doctor, for example, erythromycin ointment, mupirocin ointment, etc. Sometimes surgical treatment is also needed, which generally refers to the incision and drainage of abscesses, which can completely remove the pus and necrotic tissues, thus contributing to the subsidence of the infection.
