Referred pain (also reflective pain) is pain perceived at a location other than the site of the painful stimulus.
-->The size of referred pain is related to the intensity and duration of ongoing/evoked pain.
-->Temporal summation is a potent mechanism for generation of referred muscle pain.
-->Central hyperexcitability is important for the extent of referred pain.
-->Patients with chronic musculoskeletal pains have enlarged
referred pain areas to experimental stimuli.[vague] The proximal spread
of referred muscle pain is seen in patients with chronic musculoskeletal
pain and very seldom is it seen in healthy individuals.
-->Modality-specific somatosensory changes occur in referred areas,
which emphasize the importance of using a multimodal sensory test regime
