Causes of Shoulder Pain
The shoulder is the most movable joint in the body and vulnerable to both traumatic injuries and wear-and-tear conditions caused by repetitive activities or heavy work. It must be anchored by muscles, tendons, and ligaments to remain stable. When disrupted, painful issues may arise, such as fractures, tendinitis, infection, rheumatoid arthritis, impingement, frozen shoulder, and instability. Bone spurs are another common cause of shoulder pain, which form when the tendons between the bones deteriorate. The body reacts by generating more bone growth, causing bone-on-bone irritation at the joint.
One of the most frequent shoulder pain complaints is a result of a rotator cuff tear. The rotator cuff is the part of the shoulder that allows us to lift and extend our arms. A tear in the rotator cuff can be more common with aging, sports, or professions requiring excessive overhead activity. Many people can have a tear without pain, while others may feel a dull pain and have difficulty lifting their arm comfortably.
