What to do, What to avoid and How Physical Therapy Can Help you:

Also known as adhesive capsulitis, frozen shoulder is usually caused by inflammation. The capsule of the shoulder joint has ligaments that hold the shoulder bones to each other. When the capsule becomes inflamed, the shoulder bones are unable to move freely in the joint. This pain usually prevents you from moving your arm, and the related lack of movement can lead to stiffness and even a loss of mobility or “freezing of the shoulder”

The rotator cuff is a group of muscles and tendons in your shoulder. They help you lift and move your arms away from your body. The rotator cuff keeps the ball off the upper arm bone (humerus) in the shoulder blade socket. 

A partial or complete rotator cuff tear makes it difficult to raise and move your arm. You may have shoulder pain and arm weakness. Rotator cuff injuries are common, especially as you get older.

It occurs when there is impingement of tendons or bursa in the shoulder from bones of the shoulder. Overhead activity of the shoulder, especially repeated activity, is a risk factor for shoulder impingement syndrome. Examples include: painting, lifting, swimming, tennis, and other overhead sports. Other risk factors include bone and joint abnormalities.

Tendinitis occurs when the shoulder joint is excessively overused typically due to repetitive overhead activity or sport like basketball, volleyball etc. Poor posture is also a major factor, as this alters the normal forces on the tendons, and can set you up for tendon injury. Your tendons undergo inflammation, resulting in swelling and painful impingement when raising your arm from rest.
