Pathophysiology and Treatment of Notalgia Paresthetica- a Sensory Neuropathic Syndrome of the Back Skin: an Overview

Notalgia paresthetica (NP) is a sensory neuropathic syndrome of the back skin, classically of the unilateral infrascapula. It is primarily a localized pruritus syndrome. Notalgia paresthetica was first named in 1934 and described as episodic itching or pain on a small patch of the mid back, usually an area of skin just past easy reach. Additional features of Notalgia paresthetica may include localized burning, pain, tenderness, hyperalgesia, or dysesthesias. Notalgia paresthetica may be associated with a poorly circumscribed tan or hyperpigmented patch in the symptomatic area. Notalgia paresthetica tends to be a chronic condition with periodic remissions and exacerbations. While not life threatening and not generally associated with other co-morbidities, it does frequently decrease quality of life causing much discomfort and nuisance to the affected patients. In the present article, we have concentrated on pathophysiology, mortality, morbidity, clinical features, symptoms, causes, treatment as well as prognosis of Notalgia paresthetica. The aim of present article is to provide in depth knowledge about clinical aspects related to Notalgia paresthetica.
