I think I may have an infection from my belly ring and stretching belly. The last few days its been really hurting and today I finally took it out. After I took it out it got more swollen and red, with just a little bit of puss. I want to keep my piercing because I've had it for years.
I researched online about it:
Watch for tearing. If you decide to keep your belly button ring in, watch
for tearing or discomfort. If your belly button piercing becomes uncomfortable or infected, you'll want to remove it. If the skin around your belly button ring turns red, develops pus or starts to smell funny, you have an infection and should acquire antibiotics from your care provider.

I'm going to monitor it and hopefully it gets better.
