Cervical Radiculopathy
Neck-related nerve irritation that can cause pain, tingling, numbness, or weakness in an arm.
Overview
Cervical radiculopathy occurs when a nerve root exiting the neck becomes irritated or compressed, most often by a herniated disc or by bone spurs and narrowing where the nerve leaves the spine. The result is symptoms that follow that nerve into the shoulder, arm, or hand.
The pattern is usually distinguishable from ordinary neck pain: the arm symptoms, not the neck itself, are often the main complaint, and they may include genuine weakness in specific movements. Because each nerve root serves a distinct area, the exact distribution of your symptoms provides important information about which level is involved.
Symptoms
- Pain traveling from the neck into the shoulder, arm, or hand
- Tingling or pins-and-needles in part of the arm or specific fingers
- Numbness in a band-like distribution
- Weakness in specific arm or hand movements
- Relief or worsening with particular neck positions
- Occasionally, pain that is worse in the arm than in the neck
Possible causes
A herniated disc is a common cause, particularly in younger patients. In older patients, bone spurs and gradual narrowing of the nerve opening become more typical. Less common causes include injury, infection, or masses, which is why a thorough evaluation matters when the pattern is atypical.
How it is diagnosed
A neurologic examination tests strength, sensation, and reflexes against the known territory of each nerve root. Specific neck movements help reproduce or ease symptoms. Imaging is used when findings support it, and electrodiagnostic testing (EMG) may be recommended when the examination leaves uncertainty or when weakness is present.
Treatment options
Many cases improve over weeks with guided activity, rehabilitation, and medication to manage nerve pain. When symptoms persist or are significant, an image-guided cervical epidural steroid injection or selective nerve root block may be considered to reduce inflammation around the nerve. Surgery is reserved for progressive weakness or cases that do not respond to appropriate care.
When to see a specialist
Seek prompt assessment for worsening hand or arm weakness, loss of hand coordination or fine motor control, or problems with balance or walking. Otherwise, evaluation is appropriate when arm symptoms persist beyond a few weeks, disturb sleep, or limit the use of the arm.
