Finally, a pain signal is sent to the brain from the dorsal horn 2. Then, extracellular Ca 2+ and nitric oxide diffuse into neurons and cause exaggerated release of substance P and glutamate; this results in neuronal hyperexcitability 1. First, impulses from afferents depolarize dorsal horn neurons In FM, dorsal horn neurons become hyperresponsive to nociceptive and nonnociceptive somatic stimulation This is known as central sensitization and is thought to result in hyperalgesia and allodynia Despite extensive research, the pathogenesis of pain in FM is not clearly understood. However, central sensitization has emerged as a leading theory of disease mechanism. Staud. Arthritis Res Ther [serial online]. 2006;8:208; Henriksson.
