Peripheral neuropathy is not a single condition. It is an umbrella term covering damage to the peripheral nerves, the vast network of fibers that carries signals between the brain, spinal cord, and the rest of the body. For the more than 20 million Americans estimated to be affected by peripheral neuropathy according to the National Institute of Neurological Disorders and Stroke, finding a peripheral neuropathy specialist in Los Angeles who can identify the specific cause and extent of the damage is the starting point for any meaningful treatment.
