Left-sided neck and shoulder pain is a common medical condition affecting numerous individuals due to various causes. Exploring additional exercises and gentle neck exercises can help alleviate symptoms. According to a study, OCS, muscle strains, and cervical disc bulges are among the frequent culprits, with muscle strains often resulting from repetitive movements or maintaining static postures. Cervical disc bulges, which affect the outer layer of the soft discs separating the vertebrae in the neck, can lead to considerable pain and even numbness or weakness in the shoulder and arm areas due to pressure on the spinal nerves. Both conditions highlight the complex interplay of nerves and muscles between the neck and shoulder regions.
Cervical spondylosis, or cervical osteoarthritis, affects more than 85 percent of people over the age of 60. This condition, characterized by the wear and tear of the spinal discs in the neck, is a common cause of concurrent neck and shoulder pain, which can lead to symptoms like stiffness, pinched nerves, and intense pain. Additionally, neck pain is one of the most common musculoskeletal disorders, having an age-standardized prevalence rate of 27.0 per 1000 population in 2019.
This article will explore the causes of left-sided neck and shoulder pain and discuss effective relief methods. Understanding the potential causes of left-sided neck and shoulder pain is essential for effective management and relief.
What Causes Neck and Shoulder Pain on the Left Side?
Muscle Strain
Muscle strain is a common cause of left-sided neck and shoulder pain. It often results from repetitive movements, poor posture, or overuse of the muscles. Lifting heavy objects in an awkward position or spending extended periods in front of a computer can lead to muscle strain; frequent breaks can help mitigate this.
Cervical Disc Bulge
A cervical disc bulge occurs when one of the discs in the neck protrudes out of its normal boundary, causing the head to be held in an odd position. This can compress nearby nerves, causing pain, numbness, or weakness in the neck, shoulder, and arm. It is often a result of age-related wear and tear or previous injuries.
Cervical Stenosis
Cervical stenosis refers to the narrowing of the spinal column in the neck, often related to degenerative disc disease. This condition can pressure the spinal cord and nerves, leading to pain, muscle weakness, and other neurological conditions in the neck and shoulders. It is commonly caused by degenerative changes in the spine, such as arthritis.
Thoracic Outlet Syndrome

Thoracic outlet syndrome (TOS) occurs when nerves or blood vessels between the collarbone and first rib are compressed, affecting the levator scapulae muscle and shoulder blade region. This can cause pain in the neck and shoulder, as well as arm pain. TOS is often related to poor posture, trauma, or anatomical abnormalities such as congenital torticollis.
Inflammation
Inflammation of the muscles, tendons, or ligaments in the neck and shoulder can lead to pain due to forming a fluid-filled sac. Conditions such as tendinitis, bursitis, or arthritis can cause joint pain and discomfort on the left side of the neck and shoulder.
Pinched Nerve
A pinched nerve in the neck, also known as cervical radiculopathy, can affect nerve fibers, causing radicular pain that radiates into the shoulder and arm.. This occurs when a nerve root in the cervical spine is compressed or irritated, often due to cervical disc tears or bone spurs.
Whiplash
Whiplash injury is a severe condition commonly treated with a cervical collar after a rear-ending car accident. It results from a sudden, forceful back-and-forth neck movement, leading to muscle and ligament strain. Whiplash can cause pain and stiffness in the neck and shoulder, especially if there are previous neck injuries.
Managing Left Side Neck and Shoulder Pain
Physical Therapy Techniques
Physical therapy is an effective treatment for managing neck and shoulder pain, as it can help modulate pain signals through electrical impulses. A physical therapist can develop a personalized exercise and stretching program, a form of conservative treatment, to address the specific cause of your pain. Techniques such as manual therapy, massage, and modalities like heat or cold therapy can also help reduce pain and improve function.
Exercises for Neck and Shoulder Pain
Regular activities such as motion exercises, including movements to improve range of motion, can help alleviate neck and shoulder pain. Here are some recommended exercises that can strengthen the neck muscles:
- Neck Tilts: Slowly tilt your head to one side, bringing your ear towards your shoulder. Hold for 15-30 seconds and repeat on the other side.
- Neck Stretches: Pull your head forward, bringing your chin towards your chest. Hold for a few seconds and return to the starting position.
- Shoulder Rolls: Roll your shoulders forward and backward in a circular motion to relieve tension.
- Wall Push-ups: Stand facing a wall and place your hands on it at shoulder height. Perform push-ups against the wall to strengthen your shoulder muscles.
- Resistance Band Pulls: Pulling exercises like those performed with a resistance band can improve your neck and shoulder muscles.
- Yoga Poses for Neck and Shoulder Pain: Poses like Child’s Pose, Cat-Cow Stretch, and Extended Triangle Pose can help stretch and strengthen the neck and shoulder muscles.
Posture Correction
Bad posture significantly contributes to neck and shoulder pain and can lead to decreased range of motion, so maintaining proper posture is crucial for prevention and management. Ensure that your workstation is ergonomically set up, with your computer monitor at eye level and your chair providing adequate support. Avoid slouching or hunching forward.
Stress Management
Managing stress is essential since stress can contribute to neck and shoulder pain. Alternative therapies such as acupuncture or chiropractic care can also help. Techniques such as deep breathing exercises, meditation, and progressive muscle relaxation can help reduce stress and muscle tension.
Over-the-Counter Remedies
Moderate pain can be managed with over-the-counter painkillers like relievers and muscle relaxants, such as ibuprofen or acetaminophen. Anti-inflammatory medication can also help reduce pain and inflammation. Topical creams and patches may also provide relief for localized pain.
Self-Treatment for Left-Sided Neck and Shoulder Pain

Self-treatment measures such as applying cold packs for a few days can help alleviate mild neck and shoulder pain during everyday activities. Applying ice or a hot water bottle to the affected area, and avoiding exposure to cold temperatures, performing gentle stretching, and practicing good posture can all relieve pain. However, it is essential to avoid any activities that exacerbate your persistent neck pain.
When to Consult a Doctor
While many cases of neck and shoulder pain can be managed with self-care, medical treatment is necessary if you experience severe pain, persistent symptoms, or signs of a more serious condition requiring an accurate diagnosis, such as numbness, weakness, or difficulty breathing. A healthcare professional can conduct a physical exam, diagnose properly, and recommend appropriate treatment options, including epidural or corticosteroid injections.
Conclusion
Left-sided neck and shoulder pain can be caused by various factors, ranging from muscle strain to more severe conditions like cervical stenosis or thoracic outlet syndrome. Understanding the underlying cause of your pain is crucial for effective treatment and relief. A range of conditions can be managed by incorporating physical therapy techniques, exercises, posture correction, stress management, over-the-counter remedies, and medical treatment options, which can help manage your painful symptoms and improve your quality of life. If your symptoms persist or worsen over a period of time, consult a healthcare professional for further evaluation and treatment, including diagnostic tests and blood tests if necessary.
