Yes, this is certainly possible - especially if infection is involved.
It's best after the piercing is healed, otherwise it might get infected and swell up.
It was sucked up when you breathe in through your nose.
No, it will swell up and get even larger.
Nope. It will only close up if you have an infection
Yes
You cant do anything but get it re-pierced.
Yes
yes
6 to 8 weeks for a light heal. Keep in mind it's a new piercing and will be a new piercing until it is a year old so if you catch a cold the piercing can swell back up again.
if your parents did like the genes in the family or if you break it or hit hard it will swell up
Yes. If it is taken care of properly it can heal up to two times faster... I have both my nose and monroe done as well as other piercings.
It depends really on what type of piercing you get... See I got my nose done and that took 4 weeks to heal up :P
