What's wrong with my helix piercing?

I know it's not good to do this but a year and 4 months ago, I got my helix (top of ear) pierced with a gun. 3 of my friends got theirs pierced at the same place and had no problems, so I thought it would be safe if I got mine done too. If you're wondering, I got mine done at Merle Norman. Anyways, I twist it and clean it everyday with the antiseptic they gave me, and it still hurts quite a bit. A couple of months ago, I tried putting a sterling silver ring in and it started bleeding. I don't think it's infected though because the stud I have in is 14k gold. Does anyone know what's wrong with my ear?
