I have been to a ears nose and throat doctor, and had the scope in my throat , he said it was a burnt esophagus but I do t think so because he put me on medication and it is not working. I have a burning feeling in my tongue and in my right upper chest, with sometime sticky white saliva or mucus that i had to really work to get out of my throat, It is very frustrating. My tongue has something on it looks like a very little white , not really white maybe grey coating on my tongue but I can t tell if it is just the normal color of my tongue or not , it is a slightly different color than the tip of my tongue
