Cervical Disc Herniation
Disc material in the neck that may affect an arm nerve or the spinal cord.
General educational information is not a diagnosis or treatment recommendation for an individual.
Overview
Discs cushion the bones of the neck. A herniation occurs when inner disc material pushes through its outer covering. Nearby nerve-root irritation or compression can cause cervical radiculopathy, often felt as arm pain. A disc herniation is an anatomical finding; whether it needs treatment depends on the symptoms and examination.
Common Symptoms
Pain may travel from the neck toward the shoulder, arm, or hand. Tingling, altered sensation, and weakness can occur in the distribution of the affected nerve. Some movements aggravate symptoms. Hand clumsiness, balance problems, or walking changes suggest possible spinal cord involvement rather than an isolated pinched nerve.
Causes and Risk Factors
Discs change with age and may become less resilient. A herniation can follow lifting or another strain, but many people cannot identify a particular injury. Other age-related changes, including bone spurs, can produce similar nerve symptoms. Not every disc abnormality seen on MRI is painful.
Evaluation and Diagnosis
A clinician reviews the pattern of pain, sensation, strength, and reflexes and checks for signs of spinal cord dysfunction. MRI can show the disc and neural structures. X-rays or CT may clarify other changes. Electrical nerve testing is sometimes useful when a peripheral nerve problem, such as nerve entrapment in an arm, could explain the symptoms.
Nonsurgical Treatment Options
Many patients with cervical radiculopathy improve without surgery. Depending on the findings, care may include activity modification, physical therapy, and medication selected for the individual’s medical circumstances. Injections may sometimes reduce nerve-related pain but do not remove the herniation. Ongoing weakness or changing neurological function should be reassessed rather than managed only with pain relief.
When Surgery May Be Considered
Persistent disabling nerve-related pain despite appropriate nonsurgical treatment, or significant or progressive neurological impairment, may lead to a surgical discussion. The aim is to address the structure responsible for the symptoms. Options vary with anatomy and stability; a procedure suitable for one patient may be inappropriate for another. Surgery cannot guarantee that every neck or arm symptom will resolve.
When to Seek Neurosurgical Evaluation
Consider assessment for continuing arm pain, numbness, or weakness, particularly when function is affected or the diagnosis is uncertain. A consultation reviews whether symptoms match a particular nerve and whether there are cord-related findings. Bring imaging, medication history, and details of previous rehabilitation or injections.
Important Warning Signs
Seek urgent assessment for new or worsening weakness, new gait difficulty, or loss of hand coordination. Sudden major weakness or rapidly worsening neurological function warrants emergency care. Bladder or bowel changes together with neurological symptoms should not be deferred to a routine appointment.
Questions to Ask Your Neurosurgical Clinician
Which nerve appears affected, and does the MRI match my symptoms? Are there signs of spinal cord compression? What is the purpose of each nonsurgical option? If surgery is considered, which symptoms is it intended to address, and what alternatives and limitations should I understand?
