Dorsal scapular nerve (DSN) entrapment syndrome is an under-recognized cause of neck and shoulder pain. DSN injuries can be the origin of a well-defined chronic pain syndrome, often referred to as DSN syndrome. DSN syndrome is often characterized by a dull ache along the medial border of the scapula. The dorsal scapular nerve may be injured in the neck (at the scalenes) or in the thoracic back at the level of the rhomboids.
