Peripheral Nerve Disorders

I think what we have here is a peripheral nerve disorder and without stepping on anyone's toes in the medical profession, you need to look at what causes the peripheral nerve disorder. I think time release B5, (Calcium Pantothenate) would repair the myelin sheath to some extent. It could be a deficiency in your diet, something like spirulina would be more a more long term solution. Calcium Panto is water soluble so needs to be replaced every day. It's the time release version you want though, Hope this helps to some degree.
Find the cause, it could be nerve compression or damage after an injury.
