I don’t know how to start a discussion about burning mouth syndrome. I guess that is a form of neuropathy. Two years going on 3 years with this ailment. Trying to find answers. How does a healthy man wake up one morning with a metal taste in my mouth leaving me with limited taste and a stinging, burning tongue. So now I isolate myself because every event has to do with eating and drinking. Along with this anxiety, depression follows me. I have been to many doctors and specialists to find some answers and they have no idea what is causing this.
