Yes I also have a burning tongue. I am diagnosed with RSD and Fibro. However, the burning mouth, tongue, lips, etc. came from taking liquid chloral hydrate. It burned me as soon as I took a few sips of it. Had to be hospitalized. I must say - I am getting weekly TP INJ inside my mouth and all over my face and it has toned it down. My dentist is brilliant! He swears he can get rid of it. It's been almost 3 months now and has gone from a 10 to a 5. You may find a dentist who specializes in facial pain and try the injections. There is also a condition known as burning tongue syndrome which my Dr. treats as well. Perhaps it could be that and not RSD. Who knows what it is when we have this crazy nervous system problem. It is very frustrating to get an accurate diagnosis.
