I received a message from a piercee who was concerned about her nipple piercing, which appeared to be migrating:

Hey. 

I had both nipples done back in August. The one had to be removed about 3 months later because of rejection and now I think the other is doing the same. 

I have been under a lot of stress but I'm just not sure. It's not in the same place anymore.

My reply:

Yes, sorry-that does appear to be migration.

Did you use the same jewelry the first time? 

I noticed your jewelry appears to have a matte finish and that can cause problems, especially in a new/healing piercing. Initial jewelry should have a super-smooth, high polish mirror finish for safety. It is unclear whether the ring would have been wide enough for optimal safety when the piercing was new. The part of a ring that passes through the tissue should be relatively straight.

You should probably go ahead and remove that ring now to avoid further tissue damage.
