Interesting. I was just the opposite; RLA eliminated the burning pain completely, but had little/no effect on the numbness/"bunched-up stocking feeling". Adding pantothenic acid (B5) helped most of the cramps, shocks, & needle jabs.

Cutting out sugar (tho I'm not diabetic or pre-diabetic) has helped a great deal in reducing the numbness/"stocking" and edema.

I've been taking amitriptyline for a couple months at nighttime (chronic pain), and I seem to be getting restored feeling in my feet, but it may take more time, and I don't know if I'll ever get complete restoration (but I'll take what I can get! )

Groucho, have you tried magnesium for the arch cramps?
