When you have shoulder pain and mobility problems with no obvious cause, and there are no obvious abnormalities in the relevant imaging tests, doctors will often tell you that you have frozen shoulder. In fact, with the development of medicine and the deepening of the understanding of the anatomy and function of the shoulder, many doctors have found that the so-called frozen shoulder is just a generalized diagnosis when there is no obvious trigger for shoulder pain and impaired movement, while there are no obvious other imaging abnormalities such as rotator cuff injury, and this diagnosis has become obsolete. Most of these shoulder pains and impaired movement are actually due to chronic injury and inflammation of the shoulder tendons or bursitis, the most common being biceps longus tendonitis (estimated to account for 60-70%), and less common are subscapularis tendon injury, subacromial bursitis, pectoralis major tendon injury, large round tendon injury, deltoid tendon injury, etc. These problems are often not detected by imaging and can only be diagnosed by professional The diagnosis can only be made through professional examination. The treatment is actually very simple, a shot of closure can basically cure. For most patients with shoulder pain without obvious causes, especially severe pain, the diagnosis is based on the doctor’s deep knowledge of shoulder anatomy and function, combined with professional and meticulous physical examination techniques, and the treatment is a precise spot closure.
