Neuropathic pain is triggered by lesions to the somatosensory nervous system that alter its structure and function so that pain occurs spontaneously and responses to noxious and innocuous stimuli are pathologically amplified.

Neuropathic pain can be characterized by pain that is triggered when clothes touch the skin, spontaneous burning that feels like boiling water, bursts of pins and needles(paresthesias) in the feet upon walking , a continuous crushing pain after an amputation as if your phantom foot is being squeezed, or a band of searing pain around the body at the level at whichsensation was lost after a spinal cord injury.
