Notalgia paraesthetica is a rare entity which involves the posterior primary rami of thoracic nerves T2-T6. Patients present with a localized discomfort or pruritus on the back. The condition runs a benign course and usually resolves spontaneously. However, whilst present the symptoms can be relentless and disturbing to patients. We report three patients with notalgia paraesthetica, all of whom were helped symptomatically by the topical application of the local anaesthetic cream, EMLA (2.5% lignocaine and 2.5% prilocaine).
感觉异常性背痛是一种罕见病症，累及胸神经T2 - T6的后支。患者表现为背部局部不适或瘙痒。该病病程呈良性，通常可自行缓解。然而，症状出现时会持续存在，给患者带来困扰。我们报告了3例感觉异常性背痛患者，他们均通过局部应用局部麻醉乳膏EMLA（2.5%利多卡因和2.5%丙胺卡因）在症状上得到了缓解。
