Neuropathy is more common than you think. It has many causes with diabetes being the major cause of peripheral neuropathy, Neuropathy occurs when nerve damage interferes with functioning of the peripheral nerves. Other causes include heavy metals, side effects of chemotherapy especially the platinum drugs, and status post shingles . It can be called idiopathic neuropathy if no cause is found.
There are conventional drug therapies as neurotonin or Gabapentum can be used The dose can range from 300- 2400 mg per day in divided doses. This can be effective but many patients cannot tolerate the side effects of the drug. There are other treatments available.
I utilize the homeopathic Hypericum perforatum ( St John wort ) from Boiron in daily divided dosages. In addition I have great results with R lipoic acid ( doses 1000- 1200 mg per day), methylated B complex vitamins, curcumin ( tumeric) and even DHA. I even have seen myo -inositol have great relief from neuropathy.
I also compound in cream form a formula utilizing the above and some lidocaine and GABA. This is applied at bedtime.
