Here's the story, For as long as i can remember my tongue has been very sensative. Because of this I have never been able to eat spicy food, carbonation from pop or any form of salt is almost unbearable to eat. My tongue is discolored and as of lately has been cracking and raw... I have not been able to brush my tongue because of the pain, I do not smoke, I have tried a liquid medication for thrush once prescribed by my doctor with no results. Any advice would be greatly appreciated
