Hyperalgesia (/ˌhaɪpərælˈdʒiːziə/ or /-siə/; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) '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]
