• Pain is a complex experience of somatic mechanisms and psychological influences (affective and cognitive) and, as such, is always subjective in nature • The nervous system is capable of substantial plasticity; it can change structure and function in response to development, injury, or experience • Nociceptive or inflammatory pain arises from normal activation of pain pathways • Neuropathic pain is pain arising as a direct consequence of a lesion or disease affecting the somatosensory system (abnormal activation of pain pathways) • Pain is usually classified by mechanism (nociceptive or neuropathic), context (physiological or pathological), and location (somatic, visceral, etc.).
