Shoulder pain is often simply attributed to frozen shoulder, not only many doctors would make such a diagnosis, but also many ordinary people themselves would make such a conclusion. In fact, there are a lot of misconceptions here, as there are many causes of shoulder pain such as acromioclavicular impingement, rotator cuff tears, calcification of the supraspinatus tendon and so on. In fact, frozen shoulder is not common and is one of the less common causes of shoulder pain. It is often seen in people over 50 years old, so it is also known as “fifty shoulder”, or “frozen shoulder” because it often causes restrictions in joint movement. It is an alternative name for adhesive capsulitis. ”Most frozen shoulders are spontaneous with no obvious cause. A small number of cases may be caused by trauma or other causes. A true frozen shoulder is often characterized by pain in the shoulder in the early stages, and the pain is severe. The pain usually seems to subside in about 3-6 months, but the impaired movement of the shoulder joint in all directions becomes more pronounced. Patients have significant difficulty combing their hair, bathing, personal hygiene after urinating and defecating, and fastening bras for women. There is a simple test you can do to determine if your shoulder pain is a “frozen shoulder”. Keep your elbows close to your waist, bend your elbows 90 degrees, turn your thumbs up towards the sky, and make a fist with your remaining four fingers; while keeping your elbows close to your waist and bending your elbows 90 degrees, separate your hands to both sides and make the distance between your hands bigger. It is like doing the exercise of a tensioner, only the elbows can not move. If you cannot do this test by yourself, you can hold the above position by yourself and ask a family member to help you check whether the affected hand can be moved outward and pulled apart. If the hand on the painful side of the shoulder can move outward, most of the time it is not a “frozen shoulder”; if the hand on the painful side of the shoulder moves outward to a significantly lower degree than the healthy side, most of the time it is a “frozen shoulder”, which is commonly known as “frozen shoulder”. So if it is really “frozen shoulder”, how to choose the treatment? I will explain this in a future article. If you need to know more about it, please feel free to ask me in the comments section.
