Pain in the shoulder joint that affects upper extremity movement may be caused by frozen shoulder. It usually occurs in people around 50 years old and have a history of shoulder injury. Frozen shoulder is a self-healing disease and can be cured after 3-6 months of activity. In addition, the main manifestations of frozen shoulder are adhesions and sclerosis around the shoulder capsule and other manifestations. Shoulder pain can also be caused by rotator cuff injury or calcification of the supraspinatus muscle, which can lead to painful limitation of shoulder movement and weakness and other prominent manifestations during movement. If you have this problem, you need to go to the hospital and get an MRI of the shoulder to see if there is any supraspinatus calcification or supraspinatus muscle damage.
