A muscle tear in your shoulder can make simple tasks like reaching into a cupboard difficult. Tears in both the muscles and tendons of the shoulder are common injuries that often produce similar symptoms. Tears range from small to large, and larger tears are more likely to cause pain. Other symptoms of tears include swelling, bruising, weakness, limited motion and joint noise such as clicking or popping. Mild tears -- or strains -- often heal without lingering symptoms. Larger tears with persistent or severe symptoms may require physical therapy or surgery.
Inflammation and Bruising
The rotator cuff, which includes 4 muscles and tendons, is a common site of shoulder injury. A tear can occur due to trauma, overuse of the shoulder or from changes associated with aging. A traumatic tear may produce bruising and obvious inflammation with redness and swelling around the shoulder and upper arm. Tears due to age and overuse often have less visible inflammation, located more within the shoulder joint.
Shoulder pain is a common symptom of muscle or tendon tears in the area. The pain frequently extends into the upper arm as well. Shoulder pain often leads to difficulty sleeping at night, especially if one tries to sleep on their side. Particular injuries may have distinct pain symptoms. For example, the biceps muscle and tendon, which run along the front of the shoulder and upper arm, often cause sharp pain when they tear. If the tear is complete, a large bulging muscle will be visible in the front of the upper arm. Work and sports activities that require repetitive overhead activities can cause tears in more than one shoulder muscle or tendon, leading to more generalized soreness throughout the shoulder area.
Muscle Weakness, Limited Motion and Popping
A torn muscle or tendon is often associated with weakness in the shoulder and arm. Lifting objects and reaching the arm overhead may become difficult. The supraspinatus -- 1 of the 4 rotator cuff muscles -- is frequently injured. A torn supraspinatus causes weakness specifically when lifting the arm to the side. A torn biceps muscle creates weakness with carrying and lifting objects in front of the body. A muscle tear in your shoulder may also cause popping or clicking when moving the arm.
When to See the Doctor
Severe pain or a large loss of motion and strength is a sign of a serious injury and should be treated immediately. Also see a doctor when a shoulder muscle tear is suspected due to a trauma or fall. With trauma, other injuries are also possible, including bone fractures, dislocations, ligament tears and damaged cartilage. Nontraumatic tears, common in advanced age, can cause emotional stress and anxiety due to difficulties with daily activities. Talk to a doctor to explore the options for managing these injuries and their daily impact. If there is any doubt about the nature of the shoulder/upper body pain, seek emergency medical care, since such pain may be a symptom of a heart attack.
