Neck hernia and arm pain: when the problem is in your cervical spine

Pain radiating into the shoulder and arm, tingling fingers, a weak grip — the neck is a common culprit. What cervical disc disease looks like.

Arm pain has many causes, but when it follows a line from the neck through the shoulder into specific fingers, the cervical spine is a prime suspect.

The pattern to recognise

A cervical disc hernia presses on a nerve root as it leaves the spinal canal. Typical signs:

• Pain radiating from the neck into the shoulder blade, arm or hand
• Tingling or numbness in particular fingers (which fingers depends on which nerve)
• A weaker grip, or clumsiness with fine tasks like buttons
• Pain sometimes eased by resting the hand on top of the head

Why it should not be ignored

The cervical spinal canal also carries the spinal cord itself. Large hernias or advanced narrowing can affect the cord — a condition called myelopathy — which may show up as unsteady walking, clumsy hands on both sides or electric sensations down the body. Myelopathy tends to progress and deserves prompt specialist attention.

Treatment spectrum

Most cervical disc problems are managed without surgery: posture work, physiotherapy, medication, time. When surgery is indicated — persistent severe pain, progressive weakness or myelopathy — options range from motion-preserving disc prostheses to fusion procedures, chosen according to the anatomy.

When to seek assessment

Persistent radiating arm pain lasting more than a few weeks, any progressive weakness, or any of the myelopathy signs above are good reasons to get an MRI and a specialist opinion rather than waiting.
