Brachial Plexopathy (Adult)

What are the signs and symptoms of the injury?

Symptoms of this disorder include weakness or paralysis of the shoulder and/or upper arm. Numbness usually accompanies the weakness. Usually, there is some difficulty lifting the arm forward and rotating it outward. Partial dislocation as a result of muscle weakness may occur, causing shoulder discomfort. The muscles may become noticeably smaller, depending on the location of the nerve injury.
