burning mouth syndrome
"I have had burning mouth for 3 years.  I have found little help.  Spinal tap is clear but MRI is abnormal (symmetrical diffuse white matter).

My tongue tip burns 24/7.  I also get ice cream like headaches that last for hours, worst thing ever.

I used every anti-anxiety medications and Neurontin (gabapentin) with about 80% relief.  

I tried clonazepam in pill form 0.5mg but allowed it to dissolve in my mouth.  I had instant relief.  I was able to ween myself of all anti-anxiety medicines and Neurotin as well.  I am 3 weeks in and the world is new.  Let's see if I build a tolerance or what happens from here.  But 3 weeks without pain is awesome.

If you have burning mouth give it a shot, nothing to lose."
