I wonder if the medication just isn't a high enough dosage? Have they increased it at all?
I know Trigeminal Neuralgia is an awful disease/condition and I wouldn't wish it on my worst enemy! (well, maybe my WORST)
I just wonder if maybe they just need to increase the dose.

I know they usually start with the lowest dosage possible, like with everything else. Ask your doc -- perhaps he can raise the dose, and hopefully that will help you! I pray it does anyway! God bless & let us know, ok? Hugs, Lee
