Shoulder pain that cannot be lifted may be caused by the following reasons: 1. There may be a case of frozen shoulder. This type of disease is often due to the patient’s previous presence of cold in the shoulder joint or a traumatic injury to the shoulder joint, resulting in aseptic inflammation inside the shoulder joint. At this time, there is a large amount of inflammatory exudate inside the shoulder joint, resulting in adhesions in the joint capsule. The main manifestation of this type of disease is severe pain in the shoulder joint and severe limitation of motion. If the patient is asked to abduct the shoulder joint, the patient will often bend to the other side with a view to elevating the shoulder joint.2. There may be rotator cuff injury, which refers to a group of ligaments inside the shoulder joint that are often damaged due to impact or pulling of the shoulder joint. Once the rotator cuff is damaged, it may cause pain in the shoulder joint and lead to severe weakness in the shoulder joint. 3. There may be fractures or dislocations of the shoulder joint, which are often caused by direct impact on the shoulder joint, or by indirect violence when the patient falls to the ground with the forearm. 4. severe pain around the shoulder joint and lead to restricted movement.
