Neck Pain Left Side: Causes, Exercises and Treatments

Neck Pain Left Side Causes, Exercises and Treatments

Neck pain on the left side can be a troubling experience, affecting daily activities and overall quality of life. Understanding the underlying causes and exploring effective exercises and treatments can help manage and alleviate this discomfort. Neck pain left side can vary from minor to severe neck pain, necessitating different approaches to relief and treatment.

Causes of Neck Pain Left Side

There are a number of causes why you might experience pain in left side of neck. Here are some common causes of neck pain:

Muscle Strain or Tension

Muscle strain or tension often results from overuse, poor posture, or sudden movements. Activities like lifting heavy objects, sleeping in an awkward sleeping position, or even prolonged periods of stress can lead to muscle strain. Muscle tightness and muscle stiffness are common symptoms that can cause considerable pain.


Also known as a wry neck, torticollis involves a twisted neck that causes the head to tilt to one side. This condition can be congenital or acquired, often resulting in severe neck pain left side and limited range of motion. Acute torticollis can cause the neck muscles to contract involuntarily, leading to pain and discomfort.

Bad Posture

Bad posture, particularly when sitting at a desk or using electronic devices for extended periods, can lead to neck pain. Slouching or hunching forward puts extra strain on the neck muscles and can result in discomfort on one side. Chronic neck pain often stems from prolonged poor posture.


Whiplash is a neck injury commonly caused by car accidents or sudden impacts. The rapid back-and-forth motion can strain the neck muscles and ligaments, leading to pain and stiffness. Whiplash injury can also cause muscle spasms and severe pain.

Cervical Radiculopathy

Cervical radiculopathy occurs when a nerve in the neck is compressed or irritated, often due to a herniated disc or bone spur. This condition can cause sharp pain, numbness, or weakness that radiates down the arm. Compression of nerves and nerve roots are key factors in this condition.


Meningitis is a serious infection that causes inflammation of the membranes surrounding the brain and spinal cord. One of its symptoms is severe neck pain and stiffness, which requires immediate medical attention. Untreated neck pain in such cases can lead to permanent disability.


Inflammatory conditions such as rheumatoid arthritis can affect the cervical spine, causing pain and swelling in the neck. This can lead to chronic discomfort and mobility issues. Severe inflammation in the neck can also result from other underlying conditions.

Spinal Tumor

Though rare, spinal tumors can develop in the cervical spine, leading to neck pain. These tumors can press on the spinal cord or nerves, causing pain and other neurological symptoms. Persistent pain and severe pain can be indicative of a spinal tumor.

Congenital Abnormalities

Certain congenital abnormalities, such as abnormalities in the cervical vertebrae or muscles, can cause neck pain from an early age. These conditions may require specialized medical attention. Newborn babies with congenital abnormalities might experience neck pain as they grow.

Heart Attack

In some cases, neck pain on the left side can be a warning sign of a heart attack. This pain is often accompanied by other symptoms such as chest pain, shortness of breath, and sweating, necessitating urgent medical care. Left-sided neck pain associated with heart conditions can be severe.

Pinched Nerve

A pinched nerve occurs when too much pressure is applied to a nerve by surrounding tissues, such as bones, cartilage, muscles, or tendons. This pressure can cause pain, numbness, and tingling in the neck and down the arm. Nerve fibers and nerve cords are critical to addressing this issue.

Cervical Disc Degeneration

Cervical disc degeneration involves the breakdown of the discs in the cervical spine, leading to pain and stiffness. This condition is common with aging and can cause chronic neck pain. Degenerative conditions like cervical stenosis can exacerbate the pain.

Exercises to Avoid Neck Pain Left Side

Exercises to Avoid Neck Pain Left Side

Certain exercises can exacerbate neck pain on the left side, and it’s important to know which movements to avoid to prevent further discomfort. Here are some exercises that should be avoided if you are experiencing left-sided neck pain:

Head Tilt

  1. Movement to Avoid: Tilting your head to the right, bringing your ear toward your shoulder.
  2. Reason: This movement can strain the muscles on the left side of your neck, potentially worsening pain and tension.

Head Turn

  1. Movement to Avoid: Turning your head to the right, trying to align your chin with your shoulder.
  2. Reason: This action can exacerbate discomfort by putting additional stress on the already strained muscles and nerves on the left side of your neck.

Chin to Chest

  1. Movement to Avoid: Lowering your chin toward your chest.
  2. Reason: This motion can increase strain along the back of your neck, potentially aggravating any existing pain or stiffness.

By avoiding these exercises, you can help prevent additional strain on the neck muscles and reduce the risk of exacerbating left-sided neck pain. Focus instead on gentle movements and stretches that do not involve tilting, turning, or lowering your head excessively. Always consult with a healthcare professional before making any changes to your exercise routine, especially if you are experiencing persistent or severe neck pain.

Common Treatments for Neck Pain Left Side

Several treatments can help manage and alleviate neck pain on the left side. Here are some common options:


In severe cases where other treatments have failed, surgery may be necessary to address the underlying cause of neck pain. Surgical options vary depending on the condition but may include procedures to relieve nerve compression or stabilize the cervical spine. Severe injuries and cervical fractures might require surgical intervention.

A Hot Bath or Shower

Taking a hot bath or shower can help relax the muscles and reduce neck pain. The heat can increase blood flow and alleviate muscle tension, providing temporary relief. This method can help with temporary neck pain and minor neck pain.

Neck Support Pillows

Using a neck support pillow can help maintain proper alignment while sleeping, reducing strain on the neck muscles. These pillows are designed to support the natural curve of the neck and can prevent discomfort. An improper sleeping position can exacerbate neck pain.

Practice Gentle, Slow Stretching

Incorporating gentle, slow stretching into your daily routine can help maintain flexibility and reduce neck pain. Focus on stretches that target the neck and shoulder muscles to alleviate tension and improve range of motion. This practice can help manage moderate neck pain and chronic pain.

Neck Massage to Ease Muscle Tension

Massaging the neck muscles can help reduce tension and alleviate pain. Consider seeking professional massage therapy or using self-massage techniques to target sore areas. This can help with muscle spasms and muscle stiffness.

Posture Improvement

Improving posture can significantly reduce neck pain. Focus on maintaining a neutral spine position, keeping your head aligned with your shoulders, and avoiding slouching or hunching forward. Posture improvement can prevent minor injury and chronic neck pain.

Ergonomic Adjustments

Making ergonomic adjustments to your workspace can help prevent neck pain. Ensure your chair, desk, and computer monitor are set up to promote good posture and reduce strain on your neck. Ergonomic adjustments can prevent common conditions associated with bad posture.

Corticosteroid Injections

Corticosteroid injections can help reduce inflammation and alleviate pain in the neck. These injections are typically used for conditions such as cervical radiculopathy or severe arthritis. Steroid injections can be an effective treatment for severe pain and chronic pain.

Physical Therapy

Physical therapy can be an effective treatment for neck pain. A physical therapist can design a personalized exercise and stretching program to address your specific condition and improve neck strength and flexibility. Physical therapy can help treat severe inflammation and muscle weakness.

To effectively treat neck pain on the left side, consider the following tips:

  • Stay Active: Engage in regular physical activity to maintain overall fitness and prevent neck stiffness. This helps prevent left-side neck pain and moderate neck pain.
  • Apply Heat or Cold: Alternate between heat and cold packs to reduce pain and inflammation. This method can help with temporary neck pain.
  • Stay Hydrated: Drink plenty of water to keep your discs hydrated and maintain spinal health. Hydration is crucial for the shock absorbers in your cervical disk.
  • Take Breaks: Avoid prolonged periods of sitting or standing by taking frequent breaks to move and stretch. This can prevent muscle strain tension and compression of nerves.
