Glossary term:

Neuropathic pain

Most of the pains that we experience result from normal nerve endings being stimulated by injury, or inflammation, or by stretching of or pressure put upon the affected parts. When, however, the nerves or the sensory tracts in the spinal cord become damaged or disrupted by disease, then normal sensory signals become distorted and perceived as pain. Alternatively, pain pathways themselves generate pain signals in the absence of any peripheral stimulus.
