Define healing?
Piercing will still close even after 1 year.....
For earing piercing it is not recommended to remove the surgical
needle/ring before 3 weeks are up (speaking from experience). Even
then the wound might still be exposed even if it doesnt hurt that
badly...
Anyway I recommend after the camp because your body movements
need to adept to the new piercing espicially for ear piercing
because sometimes you dry your hair with towel might hook the
piercing or when you sleep you lie on your ear piercing
subconsciously or removing of clothes then hook until etc etc
