About 5 months ago, I started experiencing small eroded sores on the sides of my
tongue where my
tongue touches my teeth, near the back of my mouth. These patches have persisted to this day.
In the beginning, it was typically just 1 small sore at a time. These sores typically had a very thin white ring around the outside edge and areas grew slowly over a course of several days, until the white ring disappeared and the patches stopped growing.
