I just got my belly pierced like 5 days ago and my piercer said i can use peroxide & clean it 2 times a day, I've been using peroxide ever since then & i haven't had any problems, its not even hurting that much anymore. I'm not sure if this will work for you but i hope it helps :)
You need to keep the ring clean. You need to use peroxide to wipe the skin. You should also twist the ring to keep it open.
A belly button ring is a body piercing placed in a cauterized area of the belly button.
the best thing to wash a belly button ring is with anti-bacterial soap it stops the scar tissue
A lot of people have extreme sensitivity to metallic piercings, meaning, jewelry that is not 100% gold or silver. If you're belly button ring is metal, especially nickel, that might be the case. You also must be sure to clean it well, at least twice a day. Belly button rings are infected very easily.
It will get stared at more often.
If it's less than 2 months, no. If its older, you don't have to but you can.
I'd say 2-3 months. And clean after of course.
