Pus from ear piercing is mainly caused by local infection around the ear piercing or allergic infection of the local skin around the ear piercing caused by wearing earrings or studs, so for treatment, oral or static antibiotics such as cephalosporin or amoxicillin should be taken for three days. If the symptoms do not improve, it is recommended to do a drug sensitivity test and bacterial culture of the pus before ordering antibiotics, and apply sensitive and sufficient antibiotics for anti-inflammatory treatment according to the test results. Local application of Levanon drops with wet compresses around the ear piercing and treatment around the ear piercing with pus for three days can be combined with oral treatment with loratadine. If the pus does not improve or heal after aggressive anti-infection treatment, only the earring stud or earring can be removed. After aggressive treatment, the ear piercing heals and the pus is cured.
