Notalgia paresthetica: clinical features, radiological evaluation, and a novel therapeutic option.



Notalgia paresthetica (NP) is a sensory neuropathy characterized by localized pruritus and pain, presenting with or without a well-circumscribed hyperpigmented patch in the upper back. Abnormal sensations, such as burning, numbness, and paresthesia are often present in patients with NP. In this study, we clinically and radiologically analyzed patients with NP. The literature contains studies describing lidocaine treatments involving intravenous and topical applications for NP. We also investigated the effect of intradermal lidocaine injection on patients with NP.
