If you have an earache with pus, it is important to remove the earring if the procedure was done within a week. Because it is very likely that the earrings caused by the allergic reaction, irritation caused by infection, more likely because the ear piercing did not fully follow the aseptic operation, or after piercing the ear caused by the symptoms of infection. At this time, you can use povidone-iodine cotton balls or alcohol cotton balls to disinfect the surface daily, apply Bactroban ointment or gentamycin externally, and take cefradine capsules or cefuroxime sodium tablets orally. If you are allergic to cephalosporins, you can take oral roxithromycin, and try to enter the ear hole after the ear nail does not flow pus and form a sinus tract.
