Frozen shoulder is also known as “fifty shoulder” or “frozen shoulder”. It is a common orthopedic disorder in middle-aged and elderly people around the age of 50, more in women than men. To date, the cause of the disease is still unclear. It is often thought that injury to the shoulder joint and inflammation of the soft tissues are very important factors. Frozen shoulder can be a problem for many patients because the symptoms often last for a long time and severely affect the function of the limb. Many people mistake frozen shoulder for “shoulder axillitis”. They interpret the shoulder as an “axis” and as long as there is shoulder pain, it must be the disease. However, the difference between one word and the other is very different! First of all, shoulder pain is not necessarily frozen shoulder, it is most likely to be the involvement pain caused by coronary heart disease, which requires special care and exclusion to avoid misdiagnosis and delay in treatment. Secondly, shoulder pain may also be caused by cervical spondylosis. However, it is important to emphasize that cervical spondylosis causes numbness and pain in the limbs and fingers, whereas frozen shoulder does not have these symptoms and can be differentiated. What are the clinical manifestations of frozen shoulder? In most cases, frozen shoulder causes pain in the soft tissues surrounding the shoulder joint, including pain in the upper arm, not just in the “axis” of the shoulder. It is also difficult to lift the limb and, more typically, when the arm is extended backwards, movement is significantly limited and the pain is severe. The diagnosis is not difficult to make with this symptom and presentation, combined with the patient’s age of over 50 years old. So how do you understand and treat frozen shoulder? I have summarized a few words to share with you. First, frozen shoulder is a self-limiting disease. What is self-limiting? Secondly, frozen shoulder is also a disabling disease. If you are afraid to move your upper arm because of pain, when the pain disappears, the shoulder joint will become stiff and lose its original motor function. Third, the natural course of frozen shoulder is often longer, less than half a year and more than one or two years. Therefore, you should not have the idea and fear of how the treatment is ineffective. How should frozen shoulder be treated with medication? The most commonly used is oral anti-inflammatory and analgesic drugs, and you can also use local closed therapy and local heat physiotherapy, which will have a good analgesic effect. In short, having frozen shoulder is not terrible, but it is most important to protect the function of the shoulder joint.
