I have had a red spot on the top right hand side of my tongue that is about the size of a penny... It doesnt hurt and it doesnt bother me... It is hardly noticeable in the morning but at night its much more visable. I chew alot of that cinnamon gum and I to rest it right on that area thats red.. Its been red for about a week now... I went to my doctor and he took a swab of it.. He is not sure if I hurt it or not... any suggestions???????
