Actually not long at all. See it's the clothing and shirts and other layers that cause irritation to the navel piercing. If the piercing were done and left uncovered except for sleeping (bed sheets etc.) the piercing would look not bad maybe a very small red circle around the top exit point. So redness comes with the territory of clothing and irritation, this can be expected for a period of 3 to 6 months depending on the weather and the amount of clothing you wear over the navel. Remember regardless of what anyone tells you who isn't a professional body piercer navel piercing take a good year to heal and become seasoned* (* toughened up). So be nice to it and when possible give it all the fresh air you can.
It is different for everyone, for me it was really sore for the first day, then for about a week after it was painful to bend down. After that it was fine unless I knocked it.
A navel piercing can take anywhere from six months to a year to heal completely.
2-3 months
give it about a week or so it will be okay
a week at most
When you get pregnant, most care providers recommend removing your belly button ring. Even women who don't remove their rings report that belly button rings itch and pull as the belly stretches around the fifth or sixth month. There is also the risk of infection if the belly button ring scratches you or opens a small wound. If you do take out your belly button ring, the piercing hole will probably close, requiring you to re-pierce your belly button after having your baby. However, if you don't want to take out your belly button ring you may want to purchase a non-metal pregnancy piercing ring. These are flexible and two inches long to accommodate your growing belly. Pregnant women claim that this product allows them to keep their bellies pierced without the discomfort of other belly button piercing.
After 3 years chances are good it wont close, the piercing will shrink but not close completely.
Yes. If they are long though, you might want to shave or wax just to keep the hairs from getting caught in the piercing.
Depends on your body, how old the piercing is, and what size the piercing is.
Your Navel piercing shouldn't be dark. I would suggest you go back and see your piercer.
An itchy piercing is a good sign that it is healing.
if its a fresh piercing the hole will close up pretty quickly, if you've had it for a while the hole will probably take a while to close up
