Most often, a doctor should be able to diagnose peripheral neuropathy pain solely on a patient's description of symptoms and a simple neurological examination. Sometimes, however, a doctor may order special nerve tests.
An EMG/NCV are a set of diagnostic tests where a neurologist sends a small electric signal along the nerves to measure how well they are working. Unfortunately, in many peripheral neuropathy pain patients (especially those with new onset or very peripheral symptoms), these more traditional EMG/NCV tests are often completely normal, showing no signs for neuropathy.
Types of nerves tested are:
Sensory Nerves: affect sensation (pressure, chemical, temperature)
Autonomic Nerves: affect internal organ functions
Motor Nerves: affect muscles and permit voluntary movement
The five main ankle nerves include the sural, superficial peroneal, deep peroneal, saphenous and the posterior tibial.
