Shoulder joint pain and limited range of motion, often accompanied by stiffness and local discomfort

Core Typical Symptoms Shoulder joint pain: Initially mostly dull or aching pain, which may develop into persistent pain in the later stage. It worsens at night or in the morning, and may even affect sleep. The pain can radiate to the upper arm and scapular region, with obvious tenderness when pressing the painful points around the shoulder joint. Limited range of motion: This is the most characteristic symptom. Movements such as abduction, elevation, internal rotation, and external rotation of the shoulder joint are all restricted. In severe cases, daily activities like getting dressed, combing hair, and lifting arms are difficult to complete, and passive movement (movement assisted by others) is also hindered. Joint stiffness: Significant stiffness of the shoulder joint is noticeable in the morning or after prolonged sitting, which can be slightly relieved after activity. The stiffness reaches its peak during the adhesion stage, and some patients may feel the joint "tight" or "stuck". Other Accompanying Symptoms Local tenderness: Clear tender points may appear in areas such as tendons and bursae around the shoulder joint, and the pain intensifies when pressed. Muscle spasm or atrophy: Long-term pain and limited mobility may lead to spasm of shoulder muscles (such as the deltoid and supraspinatus). Mild muscle atrophy may occur in the late stage, manifested as loose shoulder lines. Pain induced or aggravated: Pain and stiffness are significantly aggravated after exposure to cold, overwork, or improper exercise, and can be relieved in a warm environment or with appropriate rest.
