Plantar wart

Been treating this for about a month and a half with just compound w patches and emery boards. The little circle in the center has been getting smaller over time after filing the skin for weeks. I went from having a annoying painful bump and having to change the way I walk. Now I’m back to a flat foot with no walking change, which I’m assuming is good. Just wondering if I should still be treating this the same way I have been or if I should stop treating, this is the only wart I’ve ever gotten so I’m not sure how to treat it.
