neuropathic pain
"Due to a toxic neuropathy which causes an excess of electrical conduction through my peripherical nervous system and results in neuralgic pain specially in my legs, arms, hands, feet, torso & face I have been taken 450mg a Day. It worked for a couple of years but now my body tolerance has reduced its pain killing efect. Don't want to increase dosage and my neurologist seems at a loss as what to prescribe."
