Welcome, TN Really Hurts,

Your TN pain sounds very severe, and it must have hit you while you were working at your truckdriving job.

I'm not sure why your neuro reacted so dismissively. Maybe he just disapproves of the gamma knife procedure in general as it does seem to be a fairly involved experience--and you might not see any improvement in the TN until a month or more later:

Gamma Knife Surgery: What it Treats, How Performed, Risks & Benefits

This is a radiation treatment, and you might want to consider whether you really would like to try it. It sounds as if you have been noticing some progress in your battle to get rid of the TN pain.

You might want to think about staying with the more conservative drug treatment that your neuro has prescribed--and you could probably do that even if you change neuros.

TN seems to be one of those neurological problems where time and more time is needed, but if you can wait it out, that's probably the best way to go. But if the pain is unbearable and you're unable to function, you should find a neuro who will be willing and able to offer you a different treatment, like the gamma knife procedure.
