Hello Dr,
I have a smooth red patch down the centre of my tongue, at times it can be a little sore but generally it does not bother me to much. Some days are better than others. Occasionally I also get tiny little red spots on the roof of my mouth, not many, maybe 4/5 at most. The spots disappear after a few days but the patch has stayed for 3-4 months now and still has not gone.
