Secondary mechanical hyperalgesia (i.e., tissue near the wound) has been seen from hours up to 7 days after surgery (hysterectomy, nephrectomy). Using electrical skin stimulation, segmental hyperalgesia is visible from hours up to 5 days postoperatively, with generalized hyperalgesia also becoming apparent at 5 days (back surgery). Many of the side effects seen with opioids occurs also secondary to opioid receptors. However, opioids can at times produce the opposite reaction in the nervous system causing hyperactivation, which leads to an increase in the pain a person feels.

Secondary hyperalgesia

Secondary hyperalgesia refers to the increase in sensitivity to mechanical nociceptive stimuli delivered outside the area of tissue injury. Previous studies have suggested that secondary hyperalgesia is mediated by a specific class of myelinated nociceptors: slowly adapting A‐fibre mechano‐ and heat‐sensitive (AMH) type I nociceptors. Secondary hyperalgesia occurs in the areas around the injured site because of nociceptor activation in the central nervous system. In a new study reported in Pain, scientists from the Université Hyperalgesia distant to the wound, or secondary hyperalgesia, occurred in response to punctate mechanical stimuli, was short-lived, and required greater forces. These results suggest that the most persistent pain behaviors in this model are largely primary hyperalgesia.

Imaging Chronic Pain and Inflammation

Secondary hyperalgesia occurs when the pain feels as if it’s spreading to a non-injured site of the body. Secondary mechanical hyperalgesia (i.e. , tissue near the wound) has been seen from hours up to 7 days after surgery (hysterectomy, nephrectomy). Using electrical skin stimulation, segmental hyperalgesia is visible from hours up to 5 days postoperatively, with generalized hyperalgesia also becoming apparent at 5 days (back surgery). Secondary hyperalgesia refers to the sensitization that occurs because of changes in spinal cord processing. For example, through a process of central sensitization, the firing of dorsal horn nociceptors can change dramatically in the setting of injury (produced by either tissue or nerve damage). Hyperalgesia is sometimes confused with tolerance.
