Wondering if my cartilage i..

OKAY I HAD MY CARTILAGE 2 YEARS BUT MY EAR GETTING SWOLLEN VERY PAINFUL DOES IT SOUND LIKE ITS GOING TO TURN INTO A KELOID OR IS IT INFECTED. AND IF IT IS INFECTED WILL MY PIERCING HAVE TO CLOSE

Cartilage is one of the hardest things to keep from getting a keloid. I had mine for 5 years then all of a sudden it just did like yours. It closed up.

Have you changed jewelry in it? Switch back and give it a week to heal... if not take it out and let it heal shut. :(
