Inhibition of cutaneous nociception by deep musculoskeletal pain. A clinical observation.
A patient is reported in whom deep musculoskeletal pain apparently blocked transmission from nociceptive cutaneous fibers in an adjacent region. When the deep musculoskeletal pain was abolished with local anesthesia, the cutaneous hypalgesia disappeared. Naloxone did not influence the hypalgesia. Possible mechanisms are discussed.
