Left shoulder pain should be alert to three diseases

The three diseases to be vigilant for left shoulder pain are scapulohumeral periarthritis, rotator cuff injury and cervical spondylosis.

1. scapulohumeral

periarthritis is a sterile inflammation caused by degeneration of soft tissue around the shoulder joint, excessive activity or cold. Its main symptoms include shoulder pain, joint stiffness and limited shoulder joint movement. As the disease progresses, the pain may gradually worsen, affecting daily life and

work.2. Rotator cuff injury

Rotator cuff injury is usually caused by external force impact, degeneration of rotator cuff tissue or chronic strain. Its main symptoms include shoulder pain, swelling of the shoulder joint and limited mobility. Especially when trying to lift the arm or perform certain movements, the pain may worsen.

3. Cervical spondylosis

Cervical spondylosis is caused by degenerative changes, long-term strain or poor posture of the cervical spine. When cervical spondylosis develops seriously, it may compress the surrounding nerve roots or spinal cord, resulting in neck and shoulder pain, upper limb numbness, weakness and other symptoms. Left shoulder pain is also one of the common manifestations of cervical spondylosis.
