What if your belly button ring falls out?

Answer 1

Well if you still have the barbell and you can get it back in the piercing without damaging the piercing, then put it in and tape it down till you can get thread on balls for the ends. If you think you have issues of not being able to get the barbell back in go see your local body piercer and have them put it in for you. They can taper the piercing and put the barbell back in without damaging the piercing.

Answer 2

Use hydrogen peroxide (H2O2). If that doesn't work, use antibiotics.

Answer 3

OOPs, time to see your body piercer.
