hey, I got my nostril piercing about a month and a half ago, using a curved-shape stud (the...twist, I think it's called). I've noticed that the inside wall of my nose is numb. I'm sure I've slept on that side of my face, which has probably caused the other end of the screw to push against my nose, but I'm worried it could be infected. I don't have any pus coming out, just numbness. what do you think?
