I'm not sure your exact situation, but you might have hope of re-piercing if you wanted to.
I had an infection in an ear piercing from Claire's when I was a kid - because piercing guns and their aftercare advice are crap.
I was able to get both ears re-piercing at an actual piercing studio last year.
You could also consider something like those over-the-ear wire hangers - especially if you painted the "wire" with liquid latex it would be pretty hard to spot unless you knew what you were looking for.
Link has both ears pierced in Twilight Princess and any time his ears are pierced that I can think of. Just sayin'. ;P
