As long as the ear hole is well maintained, it will not be inflamed, so don't worry so much! Hospitals are all hit by lasers, so be careful not to rotate the ear studs after hitting, so as not to delay the wound healing. The main reason is that you can't let water into your ear holes for 7 days, and you can't touch shampoo; Don't often touch the vicinity of the ear hole with your hands, which is easy to be infected; Three days before playing, you can smear alcohol or clear the ear hole ... generally, as long as you do this, it will not be easy to get inflamed.
