Becky, I have completed the 100% naystin medication where you rinse, gargle, and swallow rather than spit. I have improved my condition considerably. My follow up appointment is at the end of May and I will see what he says then. I will also get the results of the blood tests. Because I suffer from dry mouth and dry eyes as well as a fungal infection in my mouth he suspects Sjogrens. I am afflicted with other autoimmune problems, it is possible that I have Sjogrens. I will keep you posted later. I suppose burning mouth might have the autoimmune connection which means treat the symptoms don’t hope for a cure.
