I got my belly button pierced in July and I haven't had any problems with it till now. I got a new ring for christmas so I put it in and since its been hurting really bad. It's red, swollen, and really itchy so I figured it was rejecting it. I took it out and tried putting my old one in and now I think it's infected. I read that it was bad to take it out and now I'm scared. What should I do?
