Most of the diagnosis of frozen shoulder can be made through symptoms and physical examination, and magnetic resonance examination of shoulder joint can be done if further diagnosis is needed.
Frozen shoulder is aseptic inflammation due to shoulder joint strain, with a long course and slow development. In the early stage, it mainly manifests as paroxysmal pain in the shoulder joint, which is aggravated after activities and alleviated after resting, and occasionally severe pain will occur when the shoulder collides. The range of motion of the shoulder joint gradually decreases.
Frozen shoulder can lead to increased pain as the condition worsens, and significant pain at night during rest is an important sign of the disease. The range of motion gradually decreases, and in severe cases, it is even impossible to complete movements such as combing hair and eating.
On examination, there is obvious pressure pain around the shoulder joint, and the deltoid muscle can be atrophied in severe cases. The shoulder joint is obviously limited in abduction, forward flexion and backward extension.
With the above symptoms and physical examination, a diagnosis can be made. If further examination is needed, magnetic resonance imaging of the shoulder joint can be done to check whether there is inflammation around the shoulder joint, joint effusion, rotator cuff injury and so on.
