A friend had decades of neuropathy and finally off gabapentin and finding good help with grape seed extract. She still have some issues but much improved. Her issues are from statins and too many abx class of Fluoroquinolones

I never had the dx but deal with some with OA in my feet and Vicks Vapor Rub helps and I add drops of Lemon Oil to the drops.

Many can be deficient in B12 and magnesium for just a couple.
