Go On the web and look up Burning Moth Syndrome also known as Glossodynia I am telling you you will be very surprised and maybe cured Go GEt ALL OF YOUR BLOOD WORK DONE ALL
Sorry for the overposts, I didn't catch the "burning" in your original post.
Vitamin deficiency can indeed cause burning tongue:
"Overuse of mouth rinses and sprays may lead to burning tongue syndrome, as can anything that leads to a dry mouth. Sensitivities to certain foods and food additives, particularly to sorbic acid and benzoic acid (which are food preservatives), propylene glycol (found as a moisturizing agent in foods, drugs, and cosmetics), chicle (found in some chewing gums), and cinnamon, may play some role. Deficiencies of vitamins, including B12, folic acid, and B-complex, can cause burning mouth syndrome. Iron deficiency has also been implicated."
It's an aggravating condition, I know!
My tongue does the same thing! I'm trying to figure it out too...if you find out, please post a follow up and i'll do the same.
As an addition, I was drinking (once daily)lemon juice: 1 freshed squeezed lemon in large glass (you can buy a cheapy plastic reamer), filled the rest with water and sipped it.

My tongue had developed a "white hairy tongue" and then it disappeared. Perhaps coincidental, but at night, before bed, I was taking 2 pepto tablets (for about 2 weeks). This turned my tongue black.
I was brushing my tongue and some of it began to disappear (in small patches). Today, it is completly gone.
I associated the pepto, along with tongue brushing to the disappearance but again, perhaps coincidental.
The reason I associate it with the Pepto, is that I had been brushing my tongue in the past to no avail. However, it could have been that my tongue would have cleared up without Pepto. I dunno. lol
Might try it, if nothing else.

I am not sure. It could be a vitamin deficiency or hormonal. I would consult an oral surgeon if you have not done so far or an oral pathologist. The last doctor can be found at a dental school or a teaching hospital.
