Neck Pain Radiating to the Shoulder: Causes and Treatment

Pain spreading from one side of the neck to the shoulder is very common. The main question is whether the source is in the neck, the shoulder, or both, because they often overlap [3].

Possible causes

• Muscle strain and myofascial pain in the neck and upper back muscles
• Cervical radiculopathy: an irritated nerve root, often with arm pain, numbness or weakness [4]
• Facet joint and degenerative changes in the neck
• Shoulder problems such as rotator cuff disease, which can mimic neck pain
• Rarely, problems in the heart, lungs or other organs, which need prompt assessment

Examination

Careful examination of the neck, shoulder and nerves, sometimes supported by imaging and EMG, identifies the source [1].

Treatment

Most neck pain improves with conservative treatment [2]:

• Exercise and physiotherapy
• Manual therapy combined with exercise
• Posture and workstation advice
• Pain medicines and, in selected cases, injections

Neck or shoulder? Useful clues

• Pointing to the neck: pain that changes with neck movement, spreads below the elbow, or comes with numbness, tingling or weakness in the arm or hand
• Pointing to the shoulder: pain on the outer upper arm when lifting the arm, pain lying on the shoulder, and restricted shoulder movement
• Pointing to the muscles: a tender, tight area at the top of the shoulder (trapezius muscle) that worsens with stress, prolonged desk work or poor sleep

These clues are not definitive, and a careful examination is needed.

Risk factors

• Prolonged sitting and screen work with the head held forward
• Repetitive overhead work or heavy carrying
• Stress and poor sleep
• Previous neck injury, such as whiplash
• Age-related changes in the cervical discs and joints

Assessment

The examination includes neck and shoulder movement, nerve-root tests, muscle strength, reflexes and sensation in the arms. Imaging is not needed for most neck pain at first. MRI is used when nerve-root symptoms persist, weakness is present or a serious cause is suspected. Ultrasound is useful for the shoulder tendons. EMG (a test of nerve and muscle electrical activity) can help distinguish a pinched nerve root from a nerve trapped further down the arm.

Rehabilitation

• Neck and upper-back mobility exercises
• Strengthening of the deep neck flexor and shoulder-blade muscles
• Gradual return to normal activities and work
• For nerve-root pain, positions and exercises that ease arm symptoms, progressed over time

The programme is planned by your physical medicine and rehabilitation specialist and the physiotherapist. Whether an injection is suitable is decided after examination.

Home measures

• Set your screen at eye level and keep the keyboard close
• Take short movement breaks every 30–60 minutes
• Use a pillow that keeps your neck in a neutral position
• Apply heat for muscle tension if it helps
• Keep gently moving the neck; avoid wearing a collar for long periods

Red flags

Seek urgent care for neck pain with chest pain, shortness of breath or sweating; fever; severe sudden headache; weakness or clumsiness in the hands; problems with walking or balance; or symptoms after significant trauma.

When to see your physical medicine and rehabilitation specialist

Seek assessment if pain is severe, keeps getting worse, wakes you at night or does not start to improve within a few weeks; if numbness, weakness or any warning sign appears; or if you are unsure what your test results mean. Your physical medicine and rehabilitation (PM&R) specialist, a doctor trained to diagnose and treat musculoskeletal and nerve problems without surgery, examines you, explains the findings and plans treatment together with the physiotherapist. Whether injections or other advanced treatments are suitable for you is decided by a PM&R specialist after examination. Prof. Dr. Engin Çakar works in this field and can be consulted online or in person; otherwise, please consult a PM&R specialist near you.

To make the most of the consultation, it helps to bring:

• A short timeline of your symptoms and what makes them better or worse
• A list of your medicines and other health conditions
• Previous imaging (the images themselves, not only the reports), test results and treatment summaries
• Your questions and goals, such as returning to work, sport or a particular activity

Frequently asked questions

When is neck pain an emergency? Pain with chest pain, shortness of breath, fever, severe headache, or new weakness needs urgent assessment.

Can stress cause neck and shoulder pain? Stress can increase muscle tension and pain. See Shoulder blade pain.

Is cracking the neck harmful? Occasional noises are usually harmless. Forceful self-manipulation is not recommended.

How long does it take to improve? Many episodes of neck pain improve within a few weeks; nerve-root pain may take longer. Persistent symptoms should be re-assessed.
