Neuropathy is a symptom of another underlying illness. About 2 and a half years ago I had an autoimmune attack to my nervous system,and consequentally have neuropathy now.

But way before that happened, I had pretty severe back troubles, and I remember loosing feeling in my legs,burning,pins and needles,and extreme pain. This would also be neuropathy,although at the time I had no idea that these symptoms had there own name. I have herniated discs that had to be cut back to make room for the nerve roots that were being pinched by these discs. After my operation, I had normal sensation in my legs again.

It sounds as if your troubles could also at least in part be associated with your back,and aggrivated nerve roots. You said that you have had lower back symtoms for years. Have you seen an orthopedic or had an MRI,CT scan? Do you have a back condition?
