Nondiabetic peripheral neuropathies.
The evaluation of a peripheral neuropathy can be challenging. The history remains the most informative portion of the evaluation. Electrodiagnostic testing is important to characterize the underlying pathology. Laboratory tests should be ordered based on clinical findings. Referral to neuromuscular specialists may be helpful if the diagnosis is not forthcoming, or if ongoing treatment is required. A sizable proportion of neuropathies cannot be diagnosed. For these cases, uncomfortable symptoms can be managed successfully.
