Hi Mari,

Yes, I have googled it extensively over the past like 6 months. It could be lots of things, but my working hypothesis, given that I do have reflux, is that the reflux might be causing it.

Reflux can cause buring up to the base of the tongue and can affect all of the mouth. Reflux can increase incidence of caries, and that is a serious concern too.

At this point, I am much more concerned about my teeth and my vocal chords than I am about the sensation. Just because I don't perform doesn't mean I am willing to give up the ability to sing. The burning is meaningful to me only because it suggests that the condition is as yet uncontrolled. If my mouth burns, my vocal chords are almost certainly getting washed over with peptic acid.
