There are many injuries that may occur in the shoulder joint. The shoulder is a complex joint that allows movement in different directions. You use your shoulder and arms constantly throughout the day cleaning, lifting and to get around generally . There are also many sports and hobbies that require a lot of left shoulder movement. Depending on the injury you suffer, it is possible that certain movements can be painful to raise my arm.
The shoulder has three bones: the scapula, clavicle and humerus. The top of the humerus bone fits into a cavity in the shoulder. This socket is called the glenoid. Ligaments connect bones to bones and shoulder tendons connect the bones of the shoulder to shoulder muscles. Also located in the shoulder rotator cuff. This is a group of muscles and tendons that form a sleeve or glove around the front, back and top of the shoulder to help stabilize the joint. As these muscles contract, they pull on the tendons of the rotator cuff, which allows the shoulder to rotate upward, inward or outward.
Torn rotator cuff
According to the American Academy of Orthopaedic Surgeons, the most common cause of pain when trying to lift the arm is a tear in the rotator cuff. Damaging this structure not only causes pain when trying to lift the arm, you can do that you can not lift your arm at all. The tear can cause the muscles to weaken, which will limit your range of motion and create pain when trying to lift the arm. This is most often caused by a fall, a sports injury or overuse.
Chronic inflammatory diseases such as tendinitis or bursitis can also create pain every time you try to lift your arm. Tendinitis is an inflammation of the tendons that attach the muscles to the bones of the shoulders. Bursitis is an inflammation of the bursa located on the shoulder. These conditions can be caused by a disease such as arthritis or result from overuse of the shoulder joint. When these structures become inflamed, irritated every time you try to lift your arm.
Dislocated or separated shoulder
A dislocated shoulder occurs when the humerus bone comes out of the socket. If the shoulder is separated, no damage to the ligaments that connect the clavicle to the scapula. Both conditions produce pain when trying to lift the arm and with time will result in a loss of range of motion. A dislocated or separated shoulder is usually the result of a sports injury, a fall or some other type of impact on the shoulder joint.
Adhesive capsulitis or “frozen shoulder” is another condition that can cause pain when trying to lift the arm. This can happen if your arm has been immobilized while recovering from an injury or surgery. This condition often have symptoms mild at first, but the pain gradually worsens and slowly lose range of motion until you can no longer move the shoulder.
