Infection In Navel How Do I Care For A Belly Button/ Navel Infection?

How do I care for a belly button/ navel infection? - infection in navel

I have a piercing, but it is definitely infected. There are several red spots that are slimy and bleeds a little when you clean, but the morning there is a black substance that resembles crispy dead skin. I am very clean and the Dove shower gel so well and I was very surprised by this infection!
