J Am Acad Dermatol. 2024 Mar;90(3):465-474. doi: 10.1016/j.jaad.2023.02.070. Epub 2023 Jun 24.

Abstract

The management of erythromelalgia is challenging and requires multidisciplinary effort. Patient education is crucial as unsafe self-administered cooling techniques can lead to significant morbidity, including acral necrosis, infection, and amputation. The goal of management is pain control, reduction of flare frequency, and prevention of complications. This text is focused on the management of erythromelalgia and several other incompletely understood and under-recognized neurovascular disorders such as red scrotum syndrome, red ear syndrome, facial flushing, and complex regional pain syndrome.

Keywords: SCN9A gene; complex regional pain syndrome; erythromelalgia; flushing; red ear syndrome; red scrotum syndrome.
