Peripheral neuropathy is when the peripheral nerves (as compared to the spinal cord or brain) become the source of pain. One way to look at pain is whether it is in response to an appropriate stimulus, such as someone stepping on your toe, or whether the pain occurs for no obvious reason; malfunctioning of the nerves themselves becomes the source of the pain. Peripheral neuropathy can occur for many reasons, including as a consequence of diabetes, following trauma, toxins, and in alcoholism, to name a few causes. Peripheral neuropathy can also occur for no obvious reason.
