Frequent pus after ear piercing indicates the presence of local soft tissue infection, which needs to be treated promptly. Oral antibiotics of cephalosporin or penicillin, such as amoxicillin, cefuroxime, cefdinir, etc., can be taken. Rinse the area with hydrogen peroxide and disinfect with alcohol. Applying Bactrim after the area is clean and dry will speed up the healing of the inflammation. If there is pus in the ear, it is not recommended to continue wearing earrings at this time, and ear piercings are not recommended to be retained. If the symptoms do not improve after 4 days of treatment, go to the hospital and give antibiotics intravenously if necessary. If the localized pus flows and is accompanied by the proliferation of granulation tissue, it is necessary to completely clear the wound, otherwise there is a risk of not being able to cure.
