定义
急性疼痛是损伤或疾病的常见后果，一般在起病后不久减轻，并在完全愈合后消退。由于康复时间最长不超过 3 个月，持续超过 3 个月的疼痛即被视为慢性疼痛或顽固性疼痛。患有持续性退行性疾病（例如类风湿性关节炎）或其他慢性病症（如偏头痛或神经病理性疼痛）的患者也可能出现慢性疼痛。神经病理性疼痛以触诱发痛和痛觉过敏为特点。触诱发痛是将无害刺激感知为疼痛。在痛觉过敏中，有害刺激产生的疼痛被放大或延长。在慢性疼痛患者中，疼痛严重度可能波动，疼痛增强或疼痛的急性发作可能和活动或应激增加相关，或隐匿性发生。慢性疼痛因神经性疼痛通路持续性激活和肌肉痉挛而发生。本文将慢性疼痛作为综合征讨论，囊括了无局部性或区域性病因的非恶性病症（例如腹痛或盆腔疼痛）。
