Hyperalgesia: What It Is, Causes, Symptoms & Treatment

WebNov 5, 2014 · Mechanical hyperalgesia is one distressing symptom of neuropathic pain which is explained by central sensitization of the nociceptive system. This sensitization can be induced experimentally with the heat/capsaicin sensitization model. WebJul 1, 1999 · Hyperalgesia is thought to be due to central sensitization, to sensitization of nociceptive afferent fibers, or to both. Adding to the confusion, there are thermal or mechanical forms of allodynia and thermal or mechanical forms of hyperalgesia. Often the term hyperalgesia is used for both hyperalgesia and allodynia.
