Hi Melissa,
I totally agree with what BMW typed about the stress of things adding to our pain. I've been on neurontin for 7 of my 11 yrs of having TN. I've had to adjust amounts from time to time, but as others have said..what works for one, might not work for another. The most important thing is that we have to just pray and pray again. Then realize that the stress of worrying contributes big time to out pain level and just "take a chill pill" as family sometimes tells me..realizing that if I don't calm down at that moment, I'll end up with lots more pain later in that day.
Hugs and prayers for you that you may soon find meds that ease your level of pain a bit more.
