I've had burning tongue since Aug. 2009.
It waxes & wanes, but never goes away 24/7.
Used to drive me crazy. I can't say I'm used to it now, but I just deal with it better.
I've had it looked at by a dentist, an ENT, & GI doc. None of them knew what was causing it & none had answers on how to help it.
I feel the burning on down my esophagus sometimes.
I've have an endoscopy several times, & was on meds for acid reflux for a year or so. Endoscopy was clear every time, no signs of problems. Acid reflux meds didn't seem to be really helping with problems, so finally stopped taking them.
I also have problems swallowing. GI did a swallowing test & diagnosed me with Nutcracker Esophagus...
I get lots of jokes from my husband & kids on that one.
I was recently given Nitroglycerin tablets to use when esophagus is bad. Haven't tried them yet, but will see.
