Get something called a retainer : Its a clear nose ring . : )
A clear piercing retainer
You untwist it.
A stud definitely x
You don't put a back on a regular stud in your nose! What you do is get a proper nostril screw stud for a nostril piercing and put that in instead of the ear stud you have in your nose. If the backing comes off the regular stud in your nose and it is inhailed it can go into your lungs and then you have some serious medical issues.
To out in a nose piercing, you have toClean your noseClean the stud/ringGet the stud/ring wetGet your nose wetand thenjust jam it throughBut don't get a nose stud with a ball at the end, it hurts getting in and outso if i were you, i would get what they call the cork screw.
concealer is a good idea, but you need to make sure that it's thick enough to cover the nose stud! also, it helps if your stud is smallish cause those are easier to cover. good luck!Put a small bandaid on it. One for a wart would work. I don't think anyone is going to ask to see what is under a bandaid.
What??
no only if your nose is really sensitive
small
Yes

Go see your piercer for help.
