After cut injuries to nerves, about 70% of the persons injured are stricken with painful hypersensitivity, and at least 50% with non-causalgic pain. Clinical reports on peace-time injuries have had scarce regard to both forms. In about 80% of the injured, the painful hypersensitivity sets in within 6 months of the surgical reconstruction and ceases in half of the the patients up to the end of the second year; in the other half the disturbances seem to persist much longer. Non-causalgic pain commence earlier than the painful hypersensitivity, often already shortly after the trauma. Complete remission of this pain is rare. In the event of greater intensity, both painful hypersensitivity and non-causalgic pain entail the risk of abuse of analgesics. As to differential diagnosis, non-causalgic pain must be discriminated from genuine causalgia in which continuous pain is superimposed by paroxysms of pain.
神经切割伤后，约70%的伤者会出现疼痛性超敏反应，至少50%会出现非灼性疼痛。关于和平时期受伤的临床报告很少关注这两种形式。在约80%的伤者中，疼痛性超敏反应在手术重建后的6个月内出现，到第二年末，一半患者的症状消失；另一半患者的症状似乎持续更长时间。非灼性疼痛比疼痛性超敏反应出现得更早，通常在创伤后不久就会出现。这种疼痛完全缓解的情况很少见。如果疼痛强度较大，疼痛性超敏反应和非灼性疼痛都有滥用镇痛药的风险。在鉴别诊断方面，非灼性疼痛必须与真正的灼性神经痛相区分，真正的灼性神经痛中持续性疼痛会叠加阵发性疼痛。
