Does puss mean the infection is leaving the body or is it gettiong worse?

I've had my belly button pierced for about 3 months, and it seems it is either infected, or i am allergic to the metal. i use the surgical steel rings. It has been red and pussing in the bottom hole, and is painful to move around alot. I have been using saline (salt water) and bacitracin (kinda like neosporin) to heal it. It has been pussing more when i use it, but it doesn'y look as red as it did earlier. Does this mean the the infection is leaving my body? or is it getting worse?
