Introduction
The left shoulder experiences intermittent, needle-like pain, which may be caused by factors such as rotator cuff injury, cervical radiculopathy, or angina. It is necessary to visit a hospital for an accurate diagnosis and to relieve discomfort through general treatments and medications. Additionally, the above symptoms could also result from conditions like periarthritis of the shoulder, herpes zoster, or degenerative changes in the shoulder joint. Patients are advised to seek medical evaluation at a hospital to determine the underlying cause and receive appropriate treatment.
The left shoulder experiencing intermittent, needle-like pain may be caused by factors such as rotator cuff injury, cervical radiculopathy, or angina pectoris. It is important to seek medical evaluation at a hospital for an accurate diagnosis, and symptoms can be relieved through general treatments and medications. Specific analyses are as follows:
1. Rotator Cuff Injury
Repetitive large-range abduction movements of the shoulder joint—such as excessive clapping, playing ball games, etc.—can damage soft tissues including tendons of the subscapularis, supraspinatus, and infraspinatus muscles, leading to shoulder pain. Treatment may include medications prescribed by a doctor, such as nimesulide granules, ibuprofen tablets, and vitamin D supplements. Patients can also perform daily stretching exercises and arm-circling movements to strengthen the shoulder joint, improve local blood circulation, and promote recovery from rotator cuff injuries.
2. Cervical Radiculopathy
This condition results from degenerative changes in the cervical intervertebral discs and joints that compress or irritate corresponding segments of cervical nerve roots, causing neck pain and stiffness, often accompanied by sharp pain or numbness in the shoulder. Patients should follow medical advice and use medications such as diclofenac sodium sustained-release tablets, ibuprofen sustained-release capsules, or phenylbutazone tablets.
3. Angina Pectoris
Angina is caused by myocardial ischemia triggered by physical exertion, characterized by pressure, tightness, or suffocation in the chest area. Since the pain associated with angina can radiate via neural reflexes to areas such as the chest, neck, shoulders, arms, and upper limbs, some patients may experience pain in the shoulder, chest, or upper extremities. Medications such as trimetazidine hydrochloride tablets, atenolol tablets, or nicardipine hydrochloride injection may be used under medical supervision.
In addition, similar symptoms could also result from other conditions such as periarthritis of the shoulder (frozen shoulder), herpes zoster, or degenerative joint disease of the shoulder. Patients are advised to visit a hospital to determine the exact cause and receive appropriate, targeted treatment.
