In the acute and subacute stages, acupuncture can be used to treat frozen shoulder, which has an ideal analgesic and anti-inflammatory effect. Especially in the frozen stage, frozen shoulder can be treated by applying a single adhesion separation technique, which has been used for more than 30 years and has very good results. It only takes 3 days to cure the frozen shoulder at once, thus being able to restore the function of the shoulder joint. For frozen shoulder, the people call it fifty shoulder. Generally, it means that people around 50 years old will suffer from frozen shoulder. If there are underlying diseases such as diabetes, the onset is not necessarily limited by age, because diabetes is a factor that makes frozen shoulder good. Frozen shoulder is often divided into the following three phases: 1. Acute phase: Patients mainly show pain and the symptoms of pain will be more severe, even affecting the patient’s sleep at night, and the pain is more severe at night than during the day. 2. Subacute stage: The pain is relieved compared to the acute stage, but the function of the shoulder joint starts to be gradually restricted, and there is inflammation and adhesions. 3. Freezing stage: The pain disappears completely when this stage develops, and the most prominent manifestation is that the function of the whole shoulder joint is restricted, including supination, abduction, posterior extension and all directions of movement of the shoulder joint are extremely restricted, and basically the joint has lost its function.
