I have been under a great deal of stress and faced with a truckload of anxiety. Without getting into the details of the root of it, I was curious as to physical symptoms of anxiety. I have had a spot resurface on my tongue four time in the last 5 or 6 months. It shows up in the exact same spot, front left portion of my tongue. The spot starts off as the tongue papillae feeling a little rough then they start to disappear , it ends up being roughly the size of a pencil eraser. There is no pain or discomfort in the spot, it's not unusually hard or there's no fluid or blood present, and it always goes away in about a week, week and a half. The spot itself is flesh colored and the border seems to be a little more red in some spots and a little more white in others. Has anyone ever seen this or does anyone know what causes this?
