While on your journey for a cause and cure, be aware of your footwear. Having a physical job you may be wearing tight closed shoes. If you have relief without shoes, then you need to find socks and shoes that do not restrict. My neuropathy began in my right foot and moved to the left. Itching, burning, sweating, and a sense of it crawling up my right leg. I refused the drugs and pursued the supplements, but the most relief has come from wearing flip flops, a cool type of crocks and larger shoes when I have to. not all socks are equal either. It can really keep your sanity. I have occasional flair ups but still no drugs. I know this whole thing sucks, but don't give up.
