The first thing you should do is go to your doctor or local physician, so they can determine exactly what you have. Don't ever make up your own "healing methods", just go see someone reliable who can truly determine what the infection might be. If you can't do this, I would suggest getting in touch with your piercer. If they are as reliable as a reputable piercer would be, they would be glad to help you and willing to check it out for you and offer something that would be able to help it.
