It sounds like it isn't healed yet. Give it more time and be sure that you are keeping it clean.
Yes
See your piercer, who can help you out.
Providing it's healed from the initial piercing and it's cleaned regularly there is no need to remove it. However it may be more comfortable to remove it as blowing your nose regularly may make it sore.
You untwist it.
About 10-15 minutes
A stud definitely x
all they do is, clean the side of the nose you want piercing with a antiseptic wipe and they also clean the inside. They then draw a little dot on your nose, ask you to look into a mirror and imagine it's a nose stud and ask you if you think your happy with where it is, the then take the needle quickly pop it in where the dot is then put a nose stud in for you after, the actual piercing itself takes about 35 seconds.
look in a mirrior or if you really have to ask for help
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.
nose bleeds can burn and make new nose peircings sore but it doesnt make a difference for a healed one
NO! Don't take out a nose ring at all before its healed. This normally takes 2-4 months before its healed enough to change it. Wait at LEAST 1 year to leave it out for any amount of time. Hope this helps! =D
