What Causes Pain on Left Side of Neck Where Pulse is?

The neck is an important part of our body. It supports our head and allows it to move around. It is frequently exposed, putting its internal structures at risk of injury.

Many people suffer from temporary neck pain as a result of a variety of activities and tasks. Muscle strain from inflammation or sleeping in an awkward position is the most common cause of pain on the left side of the neck. Severe or persistent left-side neck pain, on the other hand, could signal a more serious underlying medical condition.


Neck pain on the left side can be caused by a variety of factors, including:

Tension or Muscle Strain

You may develop tension or muscle strain in the neck due to:

  • sleeping awkwardly, such as with the bent neck or twisted to one side
  • holding the phone between ear and shoulder
  • leaning forward or hunching over for several hours at a time
  • overexerting neck muscles while exercising or lifting heavy objects
  • grinding your teeth
  • falls or collisions that cause whiplash
  • non-specific causes
  • stress

These conditions can cause the below-mentioned symptoms:

  • neck pain or stiffness
  • swelling in your neck or shoulder
  • decreased range of motion and flexibility
  • muscle spasms in your shoulder
  • headaches
  • numbness or tingling in your arms


It is a condition in which your neck bends, twists, or tilts to one side. The contraction of the neck muscles causes this condition as a result of:

  • injuries or accidents
  • neurological conditions like compressed nerves or stroke
  • congenital irregularities
  • exposure to cold temperatures
  • infections
  • certain medications
  • emotional stress

Symptoms may include:

  • vomiting
  • headaches
  • pain and difficulty while straightening or moving the neck
  • balance problems
  • difficulty walking
  • vision problems
  • nausea
  • fever

Torticollis can go away on its own after a few days. Massage, heat therapy, and stretching exercises can help relax and relieve pain in the affected muscles.

Cervical Radiculopathy

A pinched nerve, also called cervical radiculopathy, occurs when a nerve root in the cervical spinal cord is compressed. A herniated disc, bone spurs, or inflammation can all contribute to this.


Neck pain which radiates down the arm and into the hand, is a symptom of cervical radiculopathy. Other signs and symptoms could include:

  • numbness or tingling in your arm
  • pins and needles
  • muscle weakness
  • reduced reflexes

Cervical Spinal Stenosis

When the spinal canal in your neck narrows, it puts pressure on the spinal cord and nerve roots, causing cervical spinal stenosis. According to studies, spinal stenosis is frequently caused by age-related changes in the spine.

Other factors to consider are:

  • rheumatoid arthritis
  • injuries of the spine
  • osteoarthritis
  • spinal cord tumors
  • Paget’s disease and the other bone conditions

Symptoms appear gradually, and many people are unaware of them in the early stages. They are as follows:

  • pain or cramping in your neck
  • weakness in your fingers, arms, or hands
  • numbness or tingling, which starts in your neck and radiates into your arms and hands

Rare Causes

Neck pain on the left side may show less common but severe medical conditions including:

  • spinal tumors
  • rheumatoid arthritis
  • congenital irregularities
  • osteoporosis
  • fibromyalgia
  • infections
  • severe injury


A doctor will conduct your physical examination to determine the cause of neck pain on the left side, during which they will assess the range of motion and pain in the affected area. They’ll look for swelling, redness, and palpable lumps under the skin. Imaging tests may also be used to look for fractures, muscle strain, or swelling in the vertebrae. These are some of them:

  • CT scans
  • MRI scans
  • X-rays

Home Remedies

The below-mentioned home treatments may help you relieve mild-to-moderate pain in the neck:

  • resting the affected area
  • applying heat by using heating pads or hot compresses
  • avoiding intense exercise and heavy lifting during the recovery period
  • taking warm baths
  • massaging the neck to relieve the muscle tension
  • reducing inflammation by using ice or cold compresses
  • stretching to improve the neck’s flexibility
  • sleeping with a pillow supporting the neck
  • gently exercising to strengthen the neck muscles
  • practicing good posture while walking, standing, and sitting

Medical Treatments

Medical treatment may be required for some types of neck pain, depending on the underlying cause. If you have severe or persistent left side neck pain, a doctor may recommend one or more of the following treatments:

  • muscle relaxants
  • corticosteroid injections
  • anti-inflammatory medication or prescription pain relief
  • occupational or physical therapy
  • surgery
  • a neck brace

Pain in left side of neck and shoulder occurs for several reasons, including heavy lifting, poor posture, and sleeping awkwardly. In most cases, tightness inside of neck improves within some days. Resting your affected area and trying home remedies help relieve the painful symptoms until your neck heals.
