Musculocutaneous nerve entrapment in the upper arm.
Wasting and weakness of the biceps and brachialis muscles can occur when the musculocutaneous nerve is compressed as it passes through the coracobrachialis muscle; there may also be impairment of sensation on the lateral aspect of the forearm. In our patient, symptoms appeared after strenuous exercise which included more than 500 press-ups each day. Electromyography and telethermic examination confirmed the diagnosis. He was advised to stop his strenuous exercises and within 3 months muscle strength and sensation had returned.
