If you have pierced ears at the earlobe and there is local swelling at the ear piercing, it means that there is local inflammation and infection, which may be caused by the irritation of the earring studs, and then you need local anti-inflammatory and anti-swelling treatment. The first step is to remove the earrings and replace them with earrings that do not cause skin irritation. The swollen earring should be disinfected with iodine twice a day, and then a local wet application of Levanox gauze should be applied for one hour. After the wet application, mupirocin ointment or erythromycin ointment should be applied locally for local anti-inflammatory treatment. After five days to a week, the swelling and inflammation of the ear hole will be slowly reduced. You should not touch your earlobes with your hands, rub, knead, squeeze or press your earlobes. Do not eat spicy and irritating food, and try to eat a light diet.
