I've had my nose pierced since March 2010. I have a stud with like an arrowhead on the inside, which is slightly bigger then the rod & stone. I have tried to change & I can get most of it out so you only see the tip of it on the inside of my nose but, if I try to go further it hurts a lot, goes red & bleeds a little. Can some please help I'm not sure what to do ?
