I had my nose done and I loved it. I had to take it out because of my new job.
You will have some swelling and soreness for about 10 days.
It is done by a 6" needle
You have to soak in sea salts every day 2xs a day to prevent infections, and help in healing.
You will have to keep makeup away from that area for about a week.
Once it heals, it looks great, I had mine done with a small diamond, surgical steel is all they will use, if they are a good piercer. Some places will only pierce with a small hoop, but I found a place to do it with the stud, I didn't want to walk around the hoop it would have been to obvious at work. If your not afraid of needles, have it done. It looks cute, I would call around a make sure your going to a good piercer.
It did not hurt at all.
When I took it out I had a small little pink dot. Now it is completely gone and you would never know I had my nose pierced!
