How do clinicians diagnose cervical radiculopathy?
Most people seek care because neck pain starts to “travel” into one arm, often with tingling, numbness, or weakness that makes everyday tasks feel hard or unsafe.¹ ⁴ A clinician will usually start by listening to your story, including when symptoms began, where the symptoms travel, what positions flare them (like looking up or turning your head), and how it affects sleep, work, and daily life.¹ ² ³
Next, they will look for a pattern that fits a specific irritated nerve in the neck. This often includes checking:
- Where symptoms show up (skin “strips” in the arm and hand)¹ ⁴
- Muscle strength in key movements like lifting your arm, straightening your elbow, extending your wrist, or gripping¹ ³
- Reflexes at the biceps, brachioradialis, and triceps¹ ³
- Sensation (touch changes) in the hand or arm¹ ³
Many clinicians also use a few simple exam tests. On their own, no single test is perfect, but a cluster of tests can make cervical radiculopathy much more likely when several are positive. These often include Spurling’s test, neck distraction (symptoms ease with gentle lifting), limited neck rotation toward the painful side, and an arm nerve tension test (ULNT1).⁵
When are imaging or nerve tests used?
Most people do not need a scan right away, especially if symptoms are improving and there are no warning signs.¹ ² Magnetic resonance imaging is usually considered when there are red flags (like possible spinal cord compression), worsening or severe weakness, or when symptoms persist despite good nonoperative care and procedures are being considered.² ³
Nerve tests (electromyography and nerve conduction studies) may be used when the diagnosis is unclear, when symptoms could be coming from a nerve trapped in the arm (like carpal tunnel), or when exam findings and imaging do not match.¹⁶
Clinical insight
What are the treatment options for cervical radiculopathy?
Most people start with the lowest-risk options, and only move to injections or surgery when symptoms are not improving enough, or when there is significant or worsening weakness.¹ ³
1. Education, reassurance, and staying active
A common goal early on is to calm the irritated nerve while keeping you safely moving. Many guidelines encourage staying as active as you can within tolerable limits, avoiding long periods in one position, and using pacing rather than strict rest.¹ ⁷ Small changes can help, like taking movement breaks from screens, adjusting your workstation, and finding a sleep position that keeps your neck more neutral.³ ⁷
A soft neck collar may sometimes be used briefly for severe acute pain, especially to help with rest, but long-term immobilization is generally avoided because it can lead to stiffness and deconditioning.¹ ³ ⁷
2. Exercise based rehabilitation
Exercise-based rehabilitation is a core part of care and often focuses on:
- Gentle neck and upper back mobility
- Deep neck muscle endurance
- Shoulder blade and upper body strength
- Gradual return to daily activities
- Symptom-limited nerve mobility exercises in some cases⁷
Overall, guidelines support a multimodal approach, usually combining exercise with other tools like manual therapy and traction when appropriate.⁷
3. Medications
Medication can help manage symptoms while recovery is underway. Guidelines and reviews commonly describe short courses of nonsteroidal anti-inflammatory drugs or other simple pain relievers as options when safe for you, and some people may be offered a medication aimed at nerve pain.³ Long-term opioid use is generally discouraged because risks can outweigh benefits.³
4. Injections
Cervical epidural steroid injections can provide short-term pain relief for some people with persistent arm-dominant nerve pain that has not improved enough with conservative care.¹⁰ Evidence for longer-term benefit is mixed, and injections do not clearly change the underlying course of the condition.¹⁰
Serious neurologic complications are rare, but they can occur, so shared decision-making matters. The US Food and Drug Administration has issued a safety communication about rare but serious neurologic events after epidural corticosteroid injections.¹¹
5. Surgery
Surgery is not needed for most people, but it can be helpful when:
- Arm pain remains severe and disabling despite a solid trial of nonoperative care
- There is progressive or severe weakness affecting function
- There are signs of cervical myelopathy, which is a different, more urgent pathway¹ ³
Common surgical options include anterior cervical discectomy and fusion, cervical disc arthroplasty (disc replacement), and posterior cervical foraminotomy in selected cases.¹ ³
Did you know?
A “pinched nerve” in the neck often has a good outlook. In a population-based study, about 90% of people were asymptomatic or only mildly symptomatic at longer-term follow-up.⁴ A few exam findings together can be more useful than any single test. When several tests in a radiculopathy cluster are positive, the likelihood of cervical radiculopathy increases meaningfully.⁵
How can I find pain relief for cervical radiculopathy?
Physical therapy is a low-risk strategy that often helps many people feel more in control while the nerve calms down. The following general guidance will often help people reduce pain and symptoms (but note this is not a substitute for medical care if symptoms are severe or changing):¹ ³ ⁴ ⁷
- Change positions often: Prolonged looking down, long drives, and static desk posture can flare symptoms, so build in short movement breaks.
- Use “just enough” movement: Gentle motion that stays within tolerable limits can help you avoid guarding and stiffness.
- Support your neck for sleep: Many people do best with a pillow setup that keeps the neck closer to neutral, rather than pushed forward or twisted.
- Pace lifting and carrying: If gripping, reaching, or carrying worsens symptoms, scale the load down and build back gradually.
- Treat flares as common, not harmful: Symptoms can vary day to day, and many cases improve over time with active care.
If arm weakness is worsening, if walking or balance changes appear, or if you develop bowel or bladder changes, seek prompt medical review since these can suggest spinal cord involvement.² ³
