I received a message from a guy about his friend's navel piercing he was concerned about (for good cause):
Hi Elayne, My friend has had her bellybutton pierced for about 7 months and its Infected and she won't take I out so I was wondering what to do for her?
You could drive her to a high quality piercer, and possibly also a doctor! Fortunately, it looks as though the problem is still localized. But infection can spread to affect a wider area. If that happens, she really should see a doctor.
Based on how it looks, her piercing is going to reject. That reddened appearance form entry to exit is a very bad sign. It indicates that the tissue holding the jewelry in has been affected and is not healthy.
If she wants to try to preserve the piercing she must get the hanging jewelry out of there right away. Hanging or dangling jewelry should never be worn on a healing piercing or one that is experiencing problems. Navel piercings frequently take 6-9 months to heal, and hanging jewelry should be avoided during that entire time.
She should put in high quality, mirror finsih, internally threaded jewelry that fits properly. Also, the bar she's wearing is far too long, and that will cause problems as well, including excess trauma.
Further, she should care for it according to accepted practice:
and do saline soaks at least twice daily:
Even if she does everything I suggest, there still may be no saving it.
