I got my cartilage on my left ear pierced yesterday. It doesn't hurt anymore but it does when I touch it, but my hair behind my ear or lay down on that side of my head. There is no redness or swelling, just pain. I can twist it with little to no pain. I got it pierced at a jewelry stand in the mall with a 14 kt gold stud. They said I could change the earring in 12 weeks. How long until it doesn't hurt anymore based on experience?
