Cervical Radiculopathy: What Is a Pinched Nerve in the Neck and Why Does It Cause Pain Elsewhere?
Cervical radiculopathy is a pinched or irritated nerve root in your neck. It happens when something presses on a nerve where it leaves the spine. This is often a worn disc or a bony spur. The pain, tingling or weakness usually travels down one arm. This is because the pressed nerve serves that arm, not just the neck itself.
Key points
- A pinched nerve in the neck often sends pain, pins and needles, or weakness into the shoulder, arm or hand.
- The most common causes are disc bulges and age-related bony spurs that narrow the space around a nerve root.
- Scans taken lying down can miss how gravity and posture add to nerve compression. Standing imaging shows the spine under real load.
- Neck alignment affects the rest of the spine. A problem higher up can lead to compensation lower down, and the other way round.
- EOS imaging shows bones, joints and alignment. For soft-tissue detail of discs or nerves, MRI is usually the better tool.
Have you had neck and arm symptoms for weeks or months without a clear answer? You are not alone. Many people go through several appointments before someone looks at the bigger picture of how their whole spine lines up.
What does a pinched nerve in the neck feel like?
A pinched nerve in the neck typically causes pain that starts in the neck and spreads into the shoulder, arm or hand. It follows the path of the affected nerve. People often describe it as sharp, burning or like an electric shock.
A sharp or burning pain that travels from the neck into the shoulder, upper arm or fingers.
Tingling or numbness in certain fingers or patches of the arm, depending on which nerve is affected.
Trouble gripping, dropping things, or a feeling that your arm is not as strong as it should be.
Limited movement in the neck, with pain often worse when you turn your head to one side.
Symptoms are often worse when you tilt or turn your head towards the affected side. Some people also notice that looking upward makes things worse. This movement narrows the space where the nerve leaves the spine.
What causes cervical radiculopathy?
Cervical radiculopathy is caused by anything that narrows or presses on the space where a nerve root leaves the neck part of the spine. The two most common causes are disc problems and bony changes from wear and tear.
The soft centre of a disc pushes outward and presses on a nearby nerve root.
Wear and tear causes small bony growths that narrow the opening where the nerve exits.
The bony tunnel (foramen) that the nerve passes through becomes too narrow and squeezes the nerve.
These changes are often linked to long-term posture habits, age-related wear, or past neck injuries. The key point is this: the compression may only become significant when you are upright and gravity is loading your spine. That is why some people have normal-looking scans taken lying down but still have real symptoms.
When should you get urgent help for neck and arm symptoms?
Most pinched nerves in the neck get better with time and the right care. However, some symptoms need urgent medical attention. Contact your doctor straight away, or go to the emergency department of your nearest hospital, if you have any of the following:
- Sudden weakness in both arms or legs, or difficulty walking.
- Loss of bladder or bowel control.
- Numbness in the groin or saddle area.
- Weakness in your arm or hand that is getting worse quickly.
These could be signs of pressure on the spinal cord itself (cervical myelopathy). This is different from a single pinched nerve root and needs prompt assessment.
Cervical radiculopathy vs cervical myelopathy
Radiculopathy affects a single nerve root, so symptoms follow one nerve path, usually into one arm. Myelopathy affects the spinal cord itself. It can cause wider problems such as balance difficulties, clumsiness in the hands, or symptoms in the legs. The two conditions can sometimes overlap. But myelopathy is considered more serious because the spinal cord does not recover as easily as a single nerve.
How is cervical radiculopathy diagnosed?
Diagnosis usually starts with a physical examination. Your doctor or therapist will test your reflexes, muscle strength and feeling in your arms and hands. They may ask you to turn or tilt your head to see if certain positions bring on your symptoms. Imaging is used to confirm what is causing the compression.
A note on MRI. EOS imaging shows bones, joints and overall spinal alignment clearly, especially under natural weight-bearing. For soft-tissue detail of discs, nerves and the spinal cord, MRI is usually the better tool. In many cases, both types of imaging together give the most complete picture.
Standard X-rays and MRI are usually taken with you lying down. This position removes the effect of gravity on your spine. Muscles relax, discs decompress slightly, and alignment shifts. The result can look reassuringly normal even when your symptoms are very real.
How does standing imaging help with a compressed nerve root in the neck?
Standing imaging captures your spine in the position where symptoms actually happen: upright and bearing weight. This matters for cervical radiculopathy. Posture and gravity directly affect how much space each nerve root has.
An EOS scan images you standing naturally, with your full body weight loading the spine. This shows the true shape of the neck curve, any forward head position, and how the neck relates to the rest of the spine below. It uses about 90% less radiation than a standard X-ray, around ten times less.
Lying-down scans remove gravity and let muscles relax. The neck curve can flatten, disc spaces may open slightly, and a forward head position disappears. The scan may look normal while the nerve is still being compressed when you stand or sit upright in daily life.
Your neck does not work on its own. The neck part of the spine sits on top of the upper back, which sits on the pelvis and legs. If your pelvis tilts, your lower back compensates. Then your upper back adjusts, and finally your neck has to adapt. A whole-body standing image shows this entire chain. Sometimes the cause of a pinched nerve in the neck is not just local wear and tear. It is a postural imbalance much further down.

Most people with a pinched nerve in the neck get better within weeks to a few months. The approach depends on how severe the compression is and what is causing it. Common approaches include:
- Changing activities. Avoiding positions that make symptoms worse, such as reaching overhead for long periods or keeping the neck bent back for a long time.
- Physiotherapy. Guided exercises to improve neck movement, strengthen supporting muscles, and address posture habits that may be adding to the problem.
- Pain management. Your doctor can advise on suitable medicine for nerve-type pain.
- Accurate diagnosis. Knowing exactly where and why the nerve is compressed helps your treating professional plan the right approach, whether non-surgical or surgical.
ScanAlign does not provide treatment. It provides detailed standing alignment images that help your treating professional see the full picture and make better decisions about your care. You can learn more about how EOS imaging assesses the spine.
Before you start treatment, or change the one you are on, it is worth getting a detailed diagnosis. Knowing whether the cause sits in the pelvis, the legs or the spine changes what will actually help.
Frequently asked questions about cervical radiculopathy
It is a pinched or irritated nerve in your neck. Something, usually a worn disc or a bony spur, presses on the nerve where it leaves the spine. This causes pain, tingling or weakness that travels into your shoulder, arm or hand.
Many people get better within six to twelve weeks with the right care. Some cases take longer. This is especially true if the underlying cause, such as a significant disc bulge or bony narrowing, is not found and addressed.
Posture alone does not usually pinch a nerve. However, holding your head forward for long periods increases the load on the neck discs and can speed up wear. This makes nerve compression more likely over time. A standing alignment assessment can show whether posture is playing a role.
Radiculopathy affects a single nerve root and usually causes symptoms in one arm. Myelopathy affects the spinal cord itself. It can cause wider problems, including balance issues, leg stiffness or clumsy hands. Myelopathy is more serious and needs a prompt medical review.
When you lie down, gravity is removed, muscles relax, and the spine decompresses slightly. A forward head position straightens out, and the spaces around nerves can open up. The compression that causes your symptoms when sitting or standing may not show up in that position.
Yes. An EOS scan uses about 90% less radiation than a standard X-ray, around ten times less. You can find more detail on the safety and FAQs page.

It can, but symptoms in both arms are less common with radiculopathy alone. If both arms are affected, or if you also have leg symptoms or balance problems, that may suggest the spinal cord is involved. You should get a prompt medical review.
Physiotherapists commonly recommend gentle neck movement exercises and nerve glides. However, exercises should be guided by a professional who has assessed your own situation. Getting accurate imaging first helps your physiotherapist target the right area.
