I have have burning mouth syndrome for many years. It was diagnosed at Mayo, yet I was given no hint of what I could do for this. I just suffered (not quite in silence) until I mentioned this to my dentist. He recalled another patient who had the same problem. Long story, short: I saw the head of oral pathology at our local dental school and he said only one thing had ever helped some of his patients. His prescription was Clonazepam 0.5 mg. 2-3 times daily. I can get by with two of these per day. It was amazing how much better I felt after beginning the Clonazepam. I was told this is one of those "no cause, no cure" medical conditions. Ah well, just add that to all of the others. My PCP now prescribes this for me and it really does help. Perhaps you will mention this to your doctor. With all good wishes, @joybringer1
