Skin damage caused by piercing the earring can easily cause skin infection. The infection should be treated with anti-infection treatment, which has two aspects, one is local medication and the other is systemic medication. Local medication includes disinfection, pus removal, debridement, and local application of antibiotic ointment, through these 4 steps, it can play the role of wound protection. Systemic medication can be oral antibacterial drugs. The most common skin infections are Gram-positive bacteria, staphylococcus and streptococcus, etc. Anti-Gram-positive drugs such as cephalosporin, erythromycin, and ofloxacin can be used. Infections caused by earrings should be temporarily removed. If the studs remain in place, the treatment is ineffective, and an irritation reaction will keep occurring, making it difficult for the wound to heal, so the studs should be removed.
