Thank you glenntaj

Yes I have taken note of that link, and will study it more. Now that I think I have found a neurologist that can help me, I hope for more answers regarding the scary feelings of " tremors and electric current down spine torso and legs. These feeling/sensation gets worse when I am tired or exhausted.
But I did mention it to this doctor. He said it was a kind of neuropathy. This was the time I ever got any response to this issue.
Actually, I had been sent to 3 differen neurologists, and I got no answer. I started to feel that no one took me seriously, and realized these doctors were not realy good.

I will fallow up next appointment is next week, will se what this doctor finds out.

I think we got off the topic of this thread re Xanax. So I will continue to fallow this neurotalk site where there is so much help to get. Perhaps you have a thread regarding "Central Pain Syndrome" I will let you know how it goes.
