A PDF which provides an excellent, thorough review of BMS (Burning Mouth Syndrome).
As this is one of my 2 main daily MS symptoms that doesn't go into remission (thus requires medication, other methods to ease pain) and I know others have reported also having BMS with Multiple Sclerosis, I hope this helps for those who have not found thorough information about a very difficult condition to diagnose and treat.
Hope this helps!

Mine's eased by Clonazepam (which is on the list). Seems I'm type 1 according to article.
