geographic tongue

What causes geographic tongue and does stress bring it on? Can it feel like a burning sensation on tongue?

[Maxy_pharma]

as general geographic tongue is of unknown cause, but there is factor my provoke:
-vitamin  deficiency (vit.B6 , B12, iron)
-auto-immune disease (lichen planus of tongue)
-infective nature (helicobacter pylori or mixed flora, thrust _candida or other atypical fungs_
-atypical sign for underlying  diseases (HIV, HCV, HBV) ;if cofused with leukoplakia

Yes u can feel burning, spicy can exaggerate it.
