I got my belly button pierced around a month and a half ago. At first it was fine and just hurt, but then it started getting red around the piercing. Now its getting crust around the lower hole of the piercing, yellow puss is coming out of it, and there is a big bump underneath it that looks like it has white stuff in it but hurt when I press on it. I have a feelings its infected, so I've been using rubbing alcohol. If it is infected, what should I do to heal it without taking it out?

I got mine done twice and both times a similar thing happened to me. It turned out my body was rejecting the piercing. You should go back to the piercer or doctor to be sure, don't use alcohol either, maybe witch hazel or dial soap
