Suggest Remedy For Hole In Stomach Due To Piercing

Dear All,
I'm kind of in a tight spot. I had my belly button pierced long time ago, and had it removed after couple of years. And the hole closed it self up. Just last year I had it pierced again, and after couple of months the previously pierced place opens up. Now I have a gapping hole in the middle of my stomach. Kindly advice on what i could do? Currently I am applying Tea Tree Oil to keep infections at bay.
