Cartilage piercings

Ash

We took my step daughter last Saturday to get her cartilage pierced (she’s 17) they told us it would swell which it did and it’s still swollen. Anyone with experience know how long to expect it to be swollen? She’s cleaning it according to the instructions they gave her and it looks normal except for the swelling. This pic was taken right after it was done. It’s not red like that anymore.
