This is one of those cautionary tales that somehow turned out all right in the end.  Of course, it took the help of three modification artists to make it happen, but I’d say it was worth it.  Here’s the story in Joeltron’s words.

Originally pierced at 12g and stretched WAY too fast to 12mm (by himself) with acrylic stretchers. Never a good thing, especially for this poor nipple! After the reconstruction they are nearly totally back to normal, except for a little bit of lost sensation.

So with the help of Howie and B-Slice, Joel was able to revert this nipple disaster.
