Heya
I had a Bad Navel Experience myself about two years ago. The pierce turned out to have been done too shallow and just WOULD NOT HEAL, bugged the hell outta me, so I just took out the jewelry and decided to have it re-done once the original pierce cleared up. About six months later, I had it re-pierced, and it's doing as well as to be expected (considering the fact this is a really hard pierce/place to heal). With all due respect, whoever told you you can't have a piercing redone sounds like the same dimwit I overheard advising someone to use 'Peach Tree Oil' in aiding the healing process.
_TEA_ TREE!! _TEA_ TREE, YOU IDIOT!
-LV, whose had her nipples re-pierced THREE times in the past five
stretching up to 8 gauge!
***In short.... It Can Be Done.
