====== Allodynia ======

Allodynia refers to central pain sensitization (increased response of neurons) following normally non-painful, often repetitive, stimulation. Allodynia can lead to the triggering of a pain response from stimuli which do not normally provoke pain.

Temperature or physical stimuli can provoke allodynia, which may feel like a burning sensation, and it often occurs after injury to a site. Allodynia is different from [[hyperalgesia]], an extreme, exaggerated reaction to a stimulus which is normally painful.
