I say go for it, if you dont like it, you can always take it out
I have quite a few piercings myself. I have my nose (my fav, I
it!!), my navel, my tongue, both ears 3 times and cartalidge(sp?). I've had my tongue double pierced twice, but I always took out the second one and just kept the one. I havent had any problems with them, I guess Im lucky. Ive also never had any problems with my nose ring as far as allergies, runny noses, etc. I barley know its there and it doesnt interfear with blowing my nose or anything. The only problem I have with it now is a duck that thinks its fun to pull it out and try to eat it:rollseyes:
I do take them all out for work, but Ive had them for so long that a day without them doesnt do anything. I also had a special nose ring made for me at a jewlers. I wanted a real diamond but didnt want it to look all big and gawdy, so I had a .05 caret diamond put in a flat, white gold bezel. It sits flat against my nose and alot of people dont even see it.
