I finally got a diagnosis of burning mouth syndrome. I have severe food allergies after an allergy doctor gave me yeast shots along with dog, cat, tree allergy shots. It took a different doctor to diagnose it. She has me on a very restrictive diet. I only eat chicken, beef, very few vegetables because of mold allergies and few fruits. I drink only rice milk and water. I also take alpha lipoic acid every day. It has taken over 2 years but I am finally getting relief. I can go almost 3 days without a breakout if I follow the diet perfectly. Sometimes I break out for no reason at all. It could be from stress also. I eat frozen mixed vegetables with chicken or beef twice a day. Boring, but I feel better. I also fry brown rice in olive oil for a change of taste.
