Introduction[edit | edit source]
IASP definition:
"Increased pain from a stimulus that normally provokes pain."[1]
Hyperalgesia is a clinical term used to described the phenomenon of an increased pain response to a painful stimuli. It does not imply a single pain mechanism, but is associated with peripheral sensitization and central sensitisation.[1]Hyperalgesia is normal protective response after tissue injury and will usually subside as healing occurs. It may however increase over time in certain conditions, such as neuropathic pain conditions.
The interpretation of the phenomenon of hyperalgesia might change with further research.
Classification[edit | edit source]
- Primary Hyperalgesia: hyperalgesia that occurs at the site of injury and is often a reflection of peripheral sanitations. It occurs as a result of reduced activation threshold and increased responsiveness of silent nociceptors
- Secondary Hyperalgesia: Sensitisation of the spinal nociceptive neurons
