Itching of the skin around the pierced ear is considered to be caused by an infection in the skin of the pierced earlobe. If the pierced ear has a stud in it, it may be caused by an allergy to the skin caused by the material of the stud. If the infection is caused by the skin of the pierced ear, you can use iodophor daily to apply to the infected skin for sterilization and anti-inflammation until the inflammation subsides, and if the skin allergy is caused by the earrings, you need to remove the earrings immediately and heal the skin allergy. It is advisable not to bring the studs and replace them with pure gold or silver studs that are not easy to cause allergies. Ear piercing is often not sterilized or not strictly sterilized if not done in a regular medical institution, which is the main cause of earlobe skin infections. Ear piercing is also a damaging operation, which not only can easily cause infections, but also can lead to infectious diseases such as AIDS if the ear piercing is not disinfected or not strictly disinfected.
