Follow-Up:
Hi Jeff, Hope your tongue condition have improved. Personally, i am also having this problem, and i've been visiting doctors for nearly a year, different drugs were introduced and it does not help at all. Till 2 weeks ago, i tried the chinese way by mixing 1/3 tea spoon of salt with water to rinse my tongue, after 2 weeks effort, 95% of my tongue has recovered. You may like to try this method, if it helps please share the method with others.
