Increased pain response to a normally painful stimulus.
An increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves.
An excessive sensitivity to pain; the opposite of hypalgesia.
Decreased threshold to a normally painful stimulus.
An increase in pain sensitivity such that normally painful stimuli feel even more painful. An expression of enhanced pain sensitivity, it can be a normal consequence of an injury or a symptom of disease. When hyperalgesia occurs in an injured area, it is called primary hyperalgesia. When it develops in areas adjacent to, distant from, or remote from an injured area, or in the absence of injury, it is called secondary hyperalgesia.
