Possible causes of left shoulder pain:
1. Periarthritis of the shoulder: This is one of the most common causes, mainly characterized by pain around the shoulder joint and restricted movement. Shoulder periarthritis frequently occurs in middle-aged and elderly individuals, especially those engaged in long-term physical labor or excessive use of the shoulder joint.
2. Rotator cuff injury: The rotator cuff is a structure composed of tendons and muscles around the shoulder joint. If torn or strained, it can cause shoulder pain. This condition is commonly seen in patients with trauma, impact injuries, or chronic overuse.
3. Cervical spondylosis: Cervical radiculopathy may compress nerves in the left upper limb, resulting in left shoulder pain. This type of pain is usually accompanied by numbness, soreness, swelling, and weakness in the upper limb.
4. Neuropathic pain: For example, nerve roots compressed due to cervical spondylosis can radiate to the shoulder, causing pain. In addition, herpes zoster can also cause severe pain in the shoulder and surrounding areas.
