I have one on my helix. Just leave the piercing earring on for 2 weeks..the wound wouldn't be that fresh then..
I used to have the same problem when changing into the stud. Eventually I asked my ex-GF to do it for me as it hurts plus I cant see the bloody back of the hole so you might want to get someone to change it for you?
Anyway it might be due to the angle in which it is was pierced not necaessarily the nerve cause if it hits the nerve you might go deaf no joke.
