At present, when shoulder pain occurs in the general population, it is considered to be frozen shoulder. The diagnostic usage of “frozen shoulder” is rather confusing and has three meanings in general: one is shoulder pain, which is not clearly diagnosed, and the other is the pain syndrome that causes shoulder dysfunction, i.e. “frozen shoulder” in the broad sense. The term has been used less and less and has been replaced by a more accurate diagnostic term. These include: rotator cuff tear, calcific supraspinatus tendonitis, subacromial bursitis, biceps longus tendon tenosynovitis, rostral or rostro-humeral ligamentitis, frozen shoulder, acromioclavicular arthritis, suprascapular nerve entrapment, subacromial impingement, and other specific localized and qualitative terms. The third term is specifically “frozen shoulder”. The exact cause of “frozen shoulder” is not known, but it may be related to autoimmune reaction or endocrine disorder. For example, many people with diabetes are found to have poor glycemic control. In general, patients feel that there may be no cause. As long as the shoulder joint is made immobile or less mobile, the disease may occur over time. As a result of the lack of movement of the joint, local metabolism is impaired and blood and lymphatic circulation is blocked, resulting in degenerative changes, exudation and fibrosis around the joint such as the joint capsule, rotator cuff, biceps tendon and rostro-humeral ligament, which greatly limits the movement of the shoulder joint. This disease is also known as “fifty shoulder” because of its high incidence around the age of fifty, and in Chinese medicine it is called “frozen shoulder” or “leaky shoulder”. The main symptom is pain in the shoulder, especially at night. There is a significant restriction in the forward flexion, abduction and internal and external rotation of the shoulder joint. Over time, deltoid atrophy can occur, and the patient will experience dysfunction in raising the arm, washing the face, combing the hair, and tying the buckle. Then how to treat frozen shoulder. I have found that most of the patients who come to see the doctor have gone through inappropriate treatment, such as relying on painkillers for treatment, looking for others to massage and break the shoulder, and using hot water for heat therapy. In fact, they all missed the best opportunity for treatment. The best opportunity is at the time of the onset of the disease, and often through reasonable rest and ice treatment can get a rapid and complete recovery. In fact, patients who come to the clinic are usually very late, and the course of the disease is usually more than 3 months old. This treatment can only be obtained through a longer scientific rehabilitation. What is scientific rehabilitation? The following is a brief introduction to you: 1, hot compresses: the temperature can be around 40 degrees, hot towels are not as easy to control the temperature of hot water bags. Each time 20-30 minutes is enough. It can properly promote local blood circulation and help the next functional exercise of shoulder joint. 2. Functional exercise of shoulder joint: The most common functional defects of shoulder joint in patients are abduction (shoulder lift), external rotation and internal rotation (shoulder turn). Therefore, the content and methods of exercise are mainly based on the deficient functions. The main movements are as follows: (1) bending and turning the shoulder (2) climbing the wall with fingers (3) pulling the hand and shoulder of the affected side with the help of the normal shoulder and hand. 3.Cold compress: Because the tissues around your shoulder joint are stretched to the maximum extent during the exercise, it is likely to cause swelling or even small bleeding of the tissues, and it is necessary to cool down such tissues to reduce the further aggravation of the limited mobility of the shoulder joint due to tissue damage and bleeding. After these 3 steps of exercise every day, the pain can be restored to the level of the previous day or even lighter the next day. If there is a tendency of significant aggravation, it means that the method of exercise may be incorrect or the exercise is too much, etc., and you need to see your doctor again immediately. Seniors don’t have to worry too much, as icing after an activity will generally have no adverse effect on your shoulder joint. Of course, the method of icing must be scientific (10 minutes at a time, 3-4 times a day, immediately after exercise). After the above 3 steps of exercises, you will generally see obvious results in 3-6 months. The whole process, and generally do not need to take any pain medication. Because the vast majority of people’s pain will not reach the level that needs to be reduced with drugs.
