Nostril piercings tend to close down very quickly. The inside of the piercing is a mucus membrane, which usually will not stay open without jewelry in it. We have seen fully healed (1+ years) nostril piercings shrink down within 10 minutes. For this reason, we suggest you always keep jewelry in your nostril piercing. If you need to hide it, try a clear acrylic retainer or small piece of clear thick fishing line (burn and flatten one end to melt into a disk). These are nearly impossible to see, and work great for sports and surgery too.
If you must leave the piercing empty, wait at least a year before trying. Then start with just a couple of minutes at a time and work your way up. Always be sure your hands, piercing and jewelry are clean when you attempt to reinsert jewelry. Using hot compresses on the inside and outside of your nostril can help relax tissue and ease reinsertion. Also, definitely lube up the jewelry (K-Y jelly or other water-based lube is best) before sliding it in. If you do annoy the piercing, soothe it afterwards with a warm saltwater soak.
About 10-15 minutes
It depends on where the piercing is. If it's in your nose then if will take a couple hours to close; if it's in your ear then probably a day or two.
Yes
It really depends on the type of piercing and long you've had the piercing.
It depends on how fast your body heals, and how long you have had the piercing. The longer you have had the piercing, the longer it will take to close. This is true for all piercings.
the hole will close over or it could get infected
yes its totally save to take a shower with your nose piercing in
It depends on where it is pierced. The lobes can take about 3 months to completely close up, where your cartilage can take 6 months to even a year to completely close up. It also depends on how long you have had the piercing. A piercing that you've had for years can take years to close (in my personal experience).
Yes it can. It all depends on your body. No real way to tell how long it would take.
It takes as long as it takes once a piercing has healed it depends on haow long you leave the jewellery out, if you are done with the piercing it can take a few days to several weeks for the piercing to actually close once it's a seasoned piercing (seasoned being over a year old).
a septum piercing never closes completly, sorry
you may NEVER take it out
