If you have shoulder pain, you should ask yourself some questions: Is your shoulder joint stiff? Is there limited movement? Does it feel dislocated? Is there any weakness in the shoulder joint that affects your daily life? If the answer to any of these questions is “yes”, you should see an orthopedic surgeon or sports medicine doctor. There are several causes of shoulder pain, including rotator cuff injury, subacromial impingement syndrome, frozen shoulder, and long biceps tendinitis. Most of them are due to shoulder injury or overuse, while the other part is caused by joint degeneration. Shoulder injuries can be caused by excessive over-the-top movements of the upper extremity, often due to repetitive high-volume training, such as swimming, tennis, baseball pitching, weightlifting, gymnastics, etc.; they can also be caused by various over-the-top activities in daily life, such as teachers writing boards, sanitation workers scrubbing glass, housewives cleaning rooms, or because of trauma, such as falling, or standing on a bus should the sudden brake pull the armrest of the shoulder sprain, etc. In general, injuries to the glenoid labrum of the shoulder joint and instability of the shoulder joint are common in younger patients, while rotator cuff injuries tend to occur in middle-aged and older patients. Some people may ignore the pain and continue to play sports, work or perform daily activities, thus aggravating the injury. For example, 40% of rotator cuff injuries have an enlarged rotator cuff tear, and 80% of them have symptoms due to the enlarged tear. As time goes on, many people tend to accept the symptoms of persistent pain, weakness of the limb and limited movement of the joint, thus forgoing further treatment and losing the opportunity to improve pain and function. The quality of life is much reduced, such as large rotator cuff tears with heavy nighttime pain, which seriously affects the patient’s sleep and leads to other disorders. And as the disease progresses further it leads to advanced shoulder stiffness and degeneration of the articular cartilage leading to the development of arthritis. Treatment with NSAIDs is effective in relieving pain and is often used in combination with physical therapy and muscle exercises. Sequestration is the injection of anesthetics and hormonal drugs into areas of definite pain, such as the subacromial, rostro-humeral ligament, acromioclavicular and glenohumeral joints, to relieve the pain and inflammatory response. It is a very effective way to treat shoulder disorders. It is required that the injection be done by a shoulder surgeon or sports medicine physician in order to prevent infection and poor results. Closed treatment is very effective for frozen shoulder, subacromial impingement, calcific tendonitis of the supraspinatus and acromioclavicular arthritis. 1 time with poor results can be re-injected after 1 week, and if 3 times with poor results or recurrence, re-injection is not recommended and surgical treatment is attempted. Surgical treatment includes open surgery and arthroscopic surgery. Although open surgery is the gold standard for rotator cuff injury, shoulder instability and other diseases, with the progress of minimally invasive arthroscopic surgery in the past 20 years, the effect of its treatment has been equivalent to open surgery in many aspects, and it has the characteristics of less damage, faster patient recovery and low incidence of complications such as infection. In China, due to the low popularity of shoulder surgery and sports medicine, the lack of specialized doctors in this field, and the lack of related health science education, many patients with shoulder disorders do not receive formal treatment, and some even believe that such diseases cannot be cured or will get better on their own. It is true that some diseases such as frozen shoulder and supraspinatus calcific tendonitis have a tendency to heal on their own, but treatment of such diseases can shorten the course of the disease, reduce pain and prevent complications. And many diseases such as shoulder instability and rotator cuff injury will develop further if left untreated. As the Jiaxing Sports Trauma Medical Center, which was jointly listed by Jiaxing Health Bureau and Sports Bureau, has accumulated rich clinical experience in surgical and non-surgical treatment of shoulder disorders and achieved satisfactory results, so if you have shoulder pain, you should seek early consultation with a sports medicine specialist.
