I Have Had A Sore On The Roof Of My

I have had a sore on the roof of my mouth for 7 days. Nothing is working to remedy it ... been to both the Dr. and dentist. Seems I have candida overgrowth as well, and have been taking a course of Lystatin (swirl and spit) since Thursday. Not noticing much of a change. Any suggestions? The sore looks like it has started to blister and is painful. Not related to a tooth.
