Does anyone else get this?

I have a myriad of symptoms, but I guess one of hte most distressing is when my left arm goes numb, i get burning sensations at same time, and my left hand also goes numb and blotchy.

I've had endless heart tests, nothing found, all results normal. To me the symptoms suggest a cardiac origin, but most of the time my heart rate is normal when it happens. Drs have often put it down to stress! I get it when I don't feel stressed. Odd and worrying.

I've had these symptoms for a couple of years now. My new doc here in Vietnam recently did lots of tests (MRI, blood tests) and found no physical reason for my symptoms, so he concluded that it's either some very strange neuro disorder (a form of epilepsy) or that it's psychological. He's put me on Neurontin 300mg 3x a day. I had some success with it, but I had good days and bad days before the pills. So i'm not sure if my good days are due to the pills or just luck / placebo effect. he wants to up my dose.
