If you have pus in your ear piercing, you need to consult a doctor promptly and clean the wound so as not to affect the healing. After cleaning the wound, give topical fusidic acid cream, Bactrim cream, and topical recombinant human epidermal growth factor gel to promote skin healing and anti-infection treatment. If there are systemic symptoms such as fever, oral antibiotic treatment is required. Do not touch water at the traumatic area to avoid aggravation of infection and do not squeeze the pus by yourself to avoid spreading the infection. After treatment, pay attention to the care of the trauma, avoid contact with water, and avoid eating spicy and irritating food, which may affect the healing of the trauma. It is best to dress the trauma with sterile gauze to avoid contamination.
