ABSTRACT
History A 50-year-old man presents with a history of an intermittently numb right arm that has become more of a problem recently after some heavy lifting. There is no history of trauma or surgery and there is no clear history of onset although the problem has been present for some months. He notices it most after sleeping, with forearm and hand numbness that wears off with movement. He also has an intermittent dull ache and impression of reduced strength, for example when trying to open jars. There is no history of Raynaud’s phenomenon, swelling or cold hand. There is no other significant medical history.
