Hello - yes, I've been taking gabapentin for about
a year now with no results. It's as if I took nothing at all for pain caused by pinched nerves. Who knows, it might help you though. I doubt there will be any unpleasant side effects for you in low to moderate doses. I took 6, 300 mg capsules/day but could have doubled it with safety. That's what my neursurgeon said anyway.
I had a friend that took a much higher dose and he said it changed his personality so I wouldn't recommend the higher doses. It seems to me you certainly don't have anything to lose based on the symptoms you describe. Good luck. j
