panic disorde
"Having burning tongue syndrome is very rare and it feels like you have an electric cable attached to your tongue.  After 3 years and 14 doctors and about 20 different medicines not to mention brain surgery NOTHING worked. One day I had a panic attack and the emergency room doctor prescribed Xanax.  It took me week and half to try it but the result was immediate. For 1st time in years I feel like living again."
