I got my cartilage piercing almost a month from now. It is still a little swollen and there's rashes behind my ear. I didn't feel any pain but its quite itchy. I got it done by a gun. Unfortunately I didn't know that having pierced by a gun is a bad idea. I've been reading horrible articles about being pierced by a gun in internet and I'm really worried. I don't want to have a cauliflower ear. What should I do? Please help. Thanks.
