Hyperalgesia (/ˌhaɪpərælˈdʒiːziə/ or /-siə/; 'hyper' from Greek ὑπέρ (huper, “over”), '-algesia' from Greek algos, ἄλγος (pain)) is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus. Prostaglandins E and F are largely responsible for sensitizing the nociceptors.[1] Temporary increased sensitivity to pain also occurs as part of sickness behavior, the evolved response to infection.[2]
