Has anyone suffering from neuropathy had any experience with ziconotide / Prialt ? This med has been developed from a chemical compound derived in poisonous snail venom. I am desperate for relief from my debilitating foot neuropathy resulting from nerve damage caused by electrocution in 2002. The Lyrica is no longer providing relief and no physician will prescribe it in the dosage that I currently need (1,500 mg in AM and 750 mg in PM).
