定义
神经病理性疼痛被描述为由代谢、营养、感染、遗传、自身免疫和/或血管病变过程引起的电性、灼痛或休克样疼痛。疼痛可自发发生，无刺激，或由有毒或无毒的刺激引起。疼痛是小纤维神经病变的特征，但即使在大纤维神经病变中，也有足够数量的小纤维受损而引起疼痛。神经病理性疼痛通常影响远端皮肤和皮下结构。疼痛可能持续或间歇性的，可描述为灼热、烧灼或冰冷。 外伤后出现复合性局部疼痛综合征，包括局部疼痛、感觉变化、体温异常、汗液分泌功能异常、皮肤颜色变化和水肿。
Neuropathic pain is described as electric, burning, or shock like, caused by metabolic, nutritional, infectious, genetic, autoimmune, and/or vasculitic processes. The pain may occur spontaneously, without provocation, or be provoked by noxious or nonnoxious stimuli. Pain is characteristic of small fibre neuropathy, but even in large fibre neuropathies, a sufficient number of small fibres may be damaged to cause pain. Neuropathic pain usually affects distal skin and subcutaneous structures. The pain may be constant or intermittent, and may be described as searing, burning, or icy cold. Complex regional pain syndrome follows trauma and comprises regional pain, sensory changes, abnormalities of temperature, sudomotor activity, colour changes of the skin, and oedema.
