Neck pain radiating
into the arm —
this has a name and a solution.

For most patients — particularly those with acute disc herniation as the cause — yes. The natural history of cervical radiculopathy from disc herniation is favorable: the majority of patients improve significantly within 6 to 12 weeks of conservative management. The herniated disc material undergoes resorption over time, reducing pressure on the nerve root, and the associated inflammation resolves. The prognosis is less predictable for radiculopathy from bony foraminal stenosis — hard bone spurs do not resorb, and symptoms that persist beyond 3 months without improvement with conservative care are more likely to require procedural intervention. Progressive neurological deficit — worsening weakness, not just pain — at any stage warrants earlier evaluation.

This is the most important question in upper extremity nerve symptom evaluation — and the one most frequently handled incompletely. A few clinical clues: If your numbness is in the thumb, index, and middle fingers, is worse with wrist flexion (Phalen test), is relieved by shaking your hand, and wakes you at night — carpal tunnel syndrome is the likely source. If your symptoms are accompanied by neck pain, worsen with head position changes, involve the entire arm rather than just the hand, and are associated with reflex changes on examination — a cervical source is more likely. Many patients have symptoms that could fit either diagnosis. The definitive test is nerve conduction studies (NCS) combined with electromyography (EMG), which measure electrical conduction through both the peripheral nerves (carpal tunnel, cubital tunnel) and the cervical nerve roots and precisely localize the compression. Dr. Katsevman performs a complete peripheral nerve examination on every patient presenting with upper extremity symptoms — regardless of what prior imaging has shown.

If you have single or two-level cervical radiculopathy from disc disease without significant instability, you may be an appropriate candidate for disc replacement rather than ACDF — and the data strongly favors disc replacement when both are technically feasible. The ProDisc-C FDA IDE trial showed a 5-fold lower reoperation rate with disc replacement vs. ACDF at 5 years (2.9% vs. 14.5%). Fusion at one level accelerates degeneration at adjacent levels; disc replacement preserves normal mechanics and protects adjacent segments. The reason most patients are offered ACDF and not disc replacement is simple: disc replacement requires specific fellowship training and device certification. A surgeon who does not perform disc replacement will not discuss it. A second opinion from a surgeon who performs both — and has disc replacement certifications — is the appropriate step before committing to ACDF for cervical radiculopathy.

These are related but distinct conditions that can coexist. Cervical radiculopathy is nerve root compression — the problem is in a single exiting nerve root, and the symptoms are in the specific arm and hand territory that nerve supplies. Cervical myelopathy is spinal cord compression — the problem is the cord itself, and the symptoms are more widespread: balance problems, gait changes, hand clumsiness, weakness in the legs, hyperreflexia. Radiculopathy causes pain and focal weakness in a nerve root pattern; myelopathy causes broader functional decline. Radiculopathy is often manageable conservatively; significant myelopathy generally warrants surgical decompression because the spinal cord, unlike nerve roots, does not recover well from sustained compression. Many patients have both simultaneously — a disc herniation compressing both the cord (myelopathy) and an exiting root (radiculopathy) at the same level.

Bilateral arm symptoms from cervical disease are important to evaluate carefully. True bilateral radiculopathy from two separate disc herniations or foraminal stenoses at different levels can occur. More significantly, bilateral upper extremity symptoms — particularly combined with any lower extremity symptoms, balance changes, or gait abnormality — may indicate cervical myelopathy rather than radiculopathy alone. Bilateral symptoms change the clinical picture meaningfully: they suggest a more central process affecting the cord or widespread nerve root involvement, and warrant MRI evaluation specifically looking at the cord signal as well as the nerve roots. Bilateral hand symptoms in a symmetric distribution also raise the possibility of bilateral carpal tunnel syndrome, which is common and entirely distinct from a cervical cause.
