I'm so sorry you are dealing with this Marie.
This page had stated that it could be caused by either an iron or vitamin B deficiency. Correcting that could solve the issue. www.hxbenefit.com/glossitis.html
Another site stated suggested these home remedies-flossing twice a day and washing the mouth twice a day with lukewarm sal***er can also help in treating the condition.

I can do more research if you need it. If I remember correctly we are in the same area. If you need help let me know.
