Symptoms & Signs
What are the signs and symptoms of the injury?
The most common complaint is shoulder weakness, especially when lifting the arm out from the side of the body. Sometimes the shoulder can still go through a full range of motion, although with less power. Within weeks of the injury, the muscle over the outside of the shoulder will become noticeably smaller. The skin over the shoulder may also become numb.
