Causes of shoulder blade pain on both sides

If you experience pain in both shoulder blades, you should pay attention to it. If you often maintain the same posture and sit for a long time, it will often cause pain in this area. This is a chronic muscle inflammation, which is especially prone to occur in middle-aged and elderly people over 40 years old. It has an important relationship with soft tissue degenerative lesions, which often causes shoulder pain and limits the mobility of the shoulder joint.

Causes of shoulder blade pain on both sides

Shoulder blade pain is mostly caused by long-term muscle spasm and deformation, or it may be caused by chronic muscle inflammation due to maintaining a posture for a long time. This disease mostly occurs in middle-aged and elderly people over 40 years old. The basic factors are degenerative lesions of soft tissues and a weakened ability to withstand various external forces.

Clinical manifestations

1. Shoulder pain: At first, the shoulder pain is paroxysmal, most of which are chronic attacks. Later, the pain gradually intensifies or becomes a sudden pain or a knife-like pain, and is continuous. The pain often worsens with climate change or after fatigue. The pain can spread to the neck and upper limbs (especially the elbows). When the shoulder is accidentally collided or pulled, it often causes tearing pain. Shoulder pain is lighter during the day and heavier at night, which is a major feature of this disease. Most patients often wake up in pain in the second half of the night and cannot fall asleep, especially cannot lie on the affected side. This situation is more obvious in those caused by blood deficiency. If the pain is caused by cold, the patient will be particularly sensitive to climate changes.

2. Limited movement: The movement of the shoulder joint in all directions may be limited, especially in abduction, elevation, internal and external rotation. As the disease progresses, long-term disuse may cause adhesion of the joint capsule and soft tissues around the shoulder, and muscle strength gradually decreases. In addition, the coracohumeral ligament is fixed in a shortened internal rotation position, which restricts the active and passive movements of the shoulder joint in all directions. Actions such as combing the hair, dressing, washing the face, and putting hands on the waist are difficult to complete. In severe cases, the function of the elbow joint may also be affected. When the elbow is flexed, the hand cannot touch the shoulder on the same side, especially when the arm is extended backward, the elbow flexion cannot be completed. 3. Fear of cold . Many patients are afraid of cold shoulders. They wrap their shoulders with cotton pads all year round. Even in summer, they dare not let the wind blow on their shoulders. 4. Tenderness Most patients can feel obvious tenderness points around the shoulder joint, most of which are in the tendon groove of the long head of the biceps brachii. Subacromial bursa, coracoid process, supraspinatus muscle attachment point, etc. 5. Spasm and atrophy: The deltoid, supraspinatus and other muscles around the shoulder may experience spasm in the early stage, and disuse muscle atrophy in the late stage, with typical symptoms such as acromion protrusion, difficulty in lifting, and difficulty in bending backward. At this time, the pain symptoms are relieved. There is mild atrophy of the deltoid muscle and spasm of the trapezius muscle. There may be obvious tenderness in the supraspinatus tendon, the long and short head tendons of the biceps brachii, and the anterior and posterior edges of the deltoid muscle. The limitations of shoulder joint are most obvious in abduction, external rotation, and extension.
