Definitely check out the shop you're planning on getting the piercing from. Make sure it is very clean and sanitary. Also you'll want to use an experienced piercer. The nose can infected easily and it will leave a lovely little lump of scar tissue. The actual piercing does sting quite a bit. It will make your eyes water, so don't wear too much eye makeup :D Be sure to clean the piercing very well. I've had my nose pierced 3 times. It closes up very easily too if you get tired of it, as long as you don't stretch I guess.
