You've got nerve.: You don't necessarily have to have diabetes to benefit from having a neuropathy. Quite frankly there are a multitude of possible causes for your symptoms. the first step is to be evaluated by a specialist who is knowledgeable with the many forms of nerve dysfunction. A starting point is comprehensive physical exam and history.
