I understand your pain. I share it with u with my own root nerve impingement. There is a herb called Capsicum Capsules Cayenne Extract and its great for choronic nerve pain. Just found out about it today and plan to try it out. This and taking liquid B stress complex vitamines is what I would try. I have the liquid stress B Complex vitamin and take it, and will soon be trying the other. Nerve damage pain is debilitating and I'm sorry your going thruthis!! *hugs*
