Displaced Sensation of Neuropathic Pain
In some types of neuropathic pain, the source of the pain and the sensation of hurt occur in different locations. In this example, one of the spongy discs that alternate with the spinal vertebrae has ruptured, leaking material that presses on an adjacent large nerve fiber (inset). Pain signals travel from the pinched fiber to the brain, which interprets them as coming from the peripheral tissues served by the fiber.
