When i was 16 (7 years ago) i pierced both my ears a 2nd time using a gun, and one healed fine, the other formed a keloid. it's so big it's covering both the holes...and so now i can't wear earrings. i was thinking of re piercing it, with a needle, because the doctor i went to said that it was the gun that caused it. is that a good idea, or will it grow back?

Side note, i've been through treatments to reduce its size, steroid injections, and they've worked, and now it's stopped growing.
