Why do I have a red wet rash around the belly button 3 months post TT? It's weeping & crusting over daily. (Photo)

TT done April 05th, belly button was the first to heal! Now it has developed a red angry rash, and weeps! It isnt open the scar is fine and closed completely. I have been washing with hibicleanse, covering it with a clean cotton t-shirt under garments but it seems to only be getting worse. My TT scar had issues and has just recently almost closed. No infection no odor - all clean but this belly button thing - what the heck is going on?
