Burning mouth syndrome – anyone else have this?

I was diagnosed with burning mouth syndrome (BMS) in 2019 after going to my GP and gastroenterologist with complaints of heartburn and throat soreness. An endoscopy proved no GERD issues and an oral pathologist ended up diagnosing me with BMS. It has been described to me as a neuropathy of the fifth cranial nerve, and the second cranial nerve which, in my case, affects the back of my throat, top of my mouth and occasionally up through my sinuses to cause a raging headache. It comes on with high stress and anxiety, sometimes with hot or cold or spicy foods, and lasts anywhere from one hour to one week.
Really doesn’t respond to any medication. Stress reduction and yoga do help a bit (placebo?) when I put my mind to it but for the most part, BMS is a bothersome undercurrent in my daily life. Just wondering if others are suffering with this as well.
Thank you!
