I had my nose pierced, and it was fine - but it closed so quickly that when I took the norml starter-type stud out to put in a thinner gemmed stud, I couldn't put the thicker one back in after only a few -hours-
The same thing happened to me. One night my nosering fell out and I couldn't put it back in when I woke up the next morning. I wish I could get my nose pierced again, but I'd have to remove the piercing for work, & there's no real use in it when the piercing closes within hours.
