Welcome to NT...sorry the entry fee is a stupid disease, or symptoms that mimic it...
I was on gabapentin (same as neurontin) for neuropathic pain with my first neuro. My current neuro only prescribes it when he is giving me time off of Requip, used for restless leg syndrome. I find that gabapentin didn't do much for me pain or spasm wise.
Keep plugging away until you have an answer...hope you're keeping a symptom journal with dates and symptoms, as well as a list of questions you want answers to...
Keep us up to date...
