Arm pain and cervical radiculopathy

Pain may travel from the neck or shoulder into the arm and can occur with tingling, numbness, or weakness. The pattern depends on which nerve root is affected, so an examination is useful when symptoms persist or interfere with normal activity.

Nerves leave the spinal cord through small openings between the neck bones and then supply the shoulder, arm, and hand. Disc irritation, age-related narrowing, or inflammation around one of these openings can disturb a nerve root. Cervical radiculopathy commonly presents with radiating arm pain and may also present with altered sensation or reduced strength.

The discomfort can feel sharp, burning, electric, or aching. Neck movement may change it, but symptoms can also be felt mainly in the arm. Similar complaints may arise from the shoulder, elbow, wrist, or a peripheral nerve, so location alone does not establish the cause.

Keep the neck and arm gently active within a comfortable range, and avoid repeatedly holding the neck in a position that clearly sends pain farther down the arm. Short changes of posture are often more manageable than prolonged bed rest or rigid guarding.

A clinician or physiotherapist can check neck movement, reflexes, sensation, grip, and muscle strength, then tailor exercises to the findings. Mention any hand clumsiness, dropping objects, previous neck injury, fever, or unexplained illness. Do not force neck stretches or use forceful manipulation when symptoms are worsening or weakness is present.

Arrange a clinical assessment if pain is persistent, recurrent, disturbing sleep, or limiting work and daily tasks. Seek prompt care for new or increasing arm or hand weakness, marked loss of sensation, severe pain after an injury, or symptoms affecting both arms.

Emergency assessment is appropriate if arm symptoms occur with new difficulty walking, loss of bladder or bowel control, numbness around the groin, or sudden chest pressure, breathlessness, sweating, faintness, or nausea. These features require evaluation for causes beyond a routine irritated neck nerve.

Ask which examination findings point to a neck nerve rather than the shoulder, elbow, or wrist; whether weakness changes the urgency; which movements are suitable; and what change in symptoms should trigger reassessment. You can also ask whether imaging would alter management, because it is not required for every episode.
