Fibromyalgi som neurogen smertetilstand

Fibromyalgia is characterised by chronic widespread pain and mechanical hyperalgesia. It is associated with a higher pain intensity, fewer pain-free intervals and more pronounced pain-related interference in function than other musculoskeletal pain conditions. Increasing evidence supports an underlying augmented central pain processing which includes sensitization of pain-transmitting neurons and dysfunction of pain inhibitory pathways. If this permanent change in the function of the nociceptive system is shown to equal fibromyalgia, the condition may be considered a neuropathic pain condition.
