What Is Radiculopathy? Understanding Pinched Nerve Roots in the Spine

If you have sharp, shooting, or burning pain running from your neck or back into your arm, chest, or leg, you may have heard the word “radiculopathy.” It can sound scary, but it simply means a problem with one of the nerve roots that leave your spine. This guide from The Pain Decoder explains what radiculopathy is, why it can be so confusing (especially in the chest area), how doctors diagnose it, and what can be done to help.

1. What is radiculopathy?

Radiculopathy means irritation or compression of a nerve root. Nerve roots are the short segments where nerves branch off from the spinal cord and leave through small openings between the bones of your spine (the vertebrae).

When something presses on, inflames, or damages a nerve root, it can cause pain, tingling, numbness, or weakness along the pathway of that nerve. Many people call this a “pinched nerve.”

Radiculopathy can happen in different parts of the spine:

Cervical radiculopathy – in the neck
Thoracic radiculopathy – in the upper and mid back/chest area
Lumbar radiculopathy – in the lower back

The symptoms you feel depend on which nerve root is affected and what is causing the problem.

2. How the spine and nerve roots work

Your spine is a column of bones (vertebrae) stacked one on top of another from your neck down to your tailbone. Between the bones are soft cushions called discs, which act like shock absorbers. Behind the vertebrae is a bony ring that protects the spinal cord.

At each level of the spine, nerve roots branch off from the spinal cord and exit through small tunnels called foramina (singular: foramen). From there, they travel to the skin, muscles, and organs of your body.

Nerve roots in the neck (cervical spine) go to the shoulders, arms, and hands.
Nerve roots in the upper and mid back (thoracic spine) wrap around the chest and abdomen.
Nerve roots in the lower back (lumbar spine) go to the hips, legs, and feet.

Anything that narrows the space around a nerve root or irritates it can lead to radiculopathy. This might be a bulging disc, bone spurs from arthritis, swelling, or rarely, an infection or tumour.

3. The three types of radiculopathy: cervical, thoracic, and lumbar

Doctors often group radiculopathy by the part of the spine where it occurs. Each area has some typical patterns.

Cervical radiculopathy (neck)

Cervical radiculopathy affects nerve roots in the neck. It often comes from a disc problem or age-related changes in the joints and ligaments of the neck.

Common symptoms include neck pain plus pain, tingling, or numbness spreading into the shoulder, arm, or hand.
You may notice weakness when gripping objects or lifting the arm.
Moving or turning the neck may worsen symptoms.

Thoracic radiculopathy (upper and mid back)

Thoracic radiculopathy affects nerve roots in the upper and mid back. It is less common than neck or lower back radiculopathy, but it can be particularly confusing because it often causes chest or abdominal pain rather than obvious back pain.

Lumbar radiculopathy (lower back)

Lumbar radiculopathy affects the nerves in the lower back. Many people know this as “sciatica” when the sciatic nerve is involved.

Common symptoms include lower back pain with shooting pain down the buttock, back of the thigh, calf, or foot.
Tingling, “pins and needles,” or numbness in the leg or foot.
Weakness, such as trouble lifting the foot or standing on tiptoes.

While cervical and lumbar radiculopathy are more widely recognised, thoracic radiculopathy is the one that is easy to miss.

4. Thoracic radiculopathy: the one that’s easy to miss

Thoracic radiculopathy involves nerve roots in the upper and mid back, from about the base of the neck down to the bottom of the rib cage. These nerves run around the body like the lines of a belt or a band, supplying the chest wall, ribs, and parts of the upper abdomen.

Because of this, pain from thoracic radiculopathy often does not feel like “back pain.” Instead, it may feel like:

A tight band or girdle of pain wrapping around one side of the chest or abdomen.
Burning, stabbing, or electric shock–like pain along a rib.
Discomfort that worsens with deep breathing, coughing, twisting, or certain postures.

This pattern can easily be mistaken for heart, lung, or stomach problems, so both patients and doctors often look in those directions first, which is appropriate. Only later does the possibility of a nerve root problem come up.

Causes of thoracic radiculopathy

Thoracic radiculopathy can develop from several different issues. Common and well-recognised causes include:

Disc herniation – A thoracic disc (the cushion between the vertebrae) bulges or ruptures and presses on a nerve root.
Degenerative changes – Age-related wear and tear can lead to bone spurs and thickened ligaments that narrow the space for the nerve.
Foraminal stenosis – The bony tunnel where the nerve exits becomes too tight, sometimes due to arthritis or a bony overgrowth.
Diabetes – Can affect nerves and sometimes cause a painful radiculopathy pattern in the trunk.
Herpes zoster (shingles) – The same virus that causes chickenpox can re-activate in a nerve root, leading to severe burning pain followed by a band of rash along the rib cage.

Less commonly, thoracic radiculopathy can be caused by growths or masses near the spine, such as benign (non-cancerous) tumours or, rarely, cancers including tumours like Ewing sarcoma. These are uncommon, but they are part of the reason a careful assessment and sometimes imaging are important when the pattern of symptoms is unusual or not improving as expected.

Why thoracic radiculopathy mimics heart or gut problems

The thoracic nerves wrap around the chest and abdomen, and the brain is not very good at telling the difference between different kinds of deep chest and trunk pain. As a result, thoracic radiculopathy can feel similar to:

Heart pain – squeezing or pressure-like pain in the chest.
Lung or pleural pain – pain with deep breathing or coughing.
Stomach or bowel problems – upper abdominal pain that seems to relate to eating or movement.

It is always vital to rule out serious causes such as heart attack, blood clots in the lungs, or major infections first. Only when those are excluded and the pattern suggests a nerve-related problem will doctors focus more on the spine.

The diagnostic challenge

Thoracic radiculopathy is relatively rare and can present in unusual ways. Some people have mainly chest or abdominal pain with very little back pain. Others have odd sensory changes, like a stripe of numbness or burning on one side of the trunk.

Because it can look like many other conditions, it may take time and several tests to reach the diagnosis. This can feel frustrating, but it does not mean your symptoms are “in your head.” It often reflects how careful doctors need to be in the chest and abdomen area.

In challenging thoracic cases, doctors may use a combination of:

Detailed history and examination – checking exactly where the pain runs, what triggers it, and how the nerves and muscles are working.
Imaging of the thoracic spine – usually MRI, sometimes CT, to look at discs, bone spurs, and any space-occupying lesions.
Electrodiagnostic testing – nerve conduction studies and electromyography (EMG) can help confirm that a thoracic nerve root is involved and rule out other nerve or muscle problems.

Case reports show that when the pattern of thoracic pain is unusual, or when standard treatment does not help, a thorough re-examination can uncover rare causes such as tumours or more complex spinal narrowing. Again, these are not common, but they’re a reminder that persistent or puzzling symptoms deserve proper attention.

5. What causes radiculopathy?

Across the whole spine, radiculopathy can develop for several reasons. Some of the main causes include:

Disc herniation (slipped disc) – The soft inner part of a disc pushes out through a tear in the outer ring and presses on a nerve root.
Degenerative disc disease and arthritis – With age, discs dry out and joints in the spine wear down. This can cause bone spurs and thickened ligaments that narrow the space for the nerves.
Spinal stenosis – General narrowing of the spinal canal or nerve exit holes, often from age-related changes.
Injury or trauma – A fall, accident, or lifting injury can damage discs, joints, or bones and compress a nerve root.
Infections – Infections in or around the spine can cause swelling and pressure on nerve roots.
Tumours or cysts – Both non-cancerous and cancerous growths near the spine can crowd the nerve roots. These are rare but important to consider when symptoms don’t fit the usual pattern.
Metabolic or systemic conditions – For example, diabetes can affect nerves and sometimes show up with a radiculopathy pattern.

In many people, more than one factor is present. For example, a person with mild age-related changes may develop symptoms after a minor injury or period of heavy physical work.

6. What does radiculopathy feel like?

Radiculopathy can feel very different from one person to another, but some common features include:

Shooting or electric shock–like pain that travels from the spine into an arm, chest, or leg.
Burning or stabbing pain along a narrow strip of skin (a “dermatome”) that matches a particular nerve root.
Tingling or “pins and needles”.
Numbness in a particular patch of skin.
Weakness in certain muscles connected to that nerve.
Symptoms that change with position, such as worsening when bending, twisting, coughing, or sitting for a long time, and easing when lying down or gently walking.

In thoracic radiculopathy, people often describe a tight band or girdle of pain around one side of the chest or abdomen, sometimes with a clear upper and lower border. This can be constant or come in bursts.

7. How is radiculopathy diagnosed?

There is no single test that diagnoses radiculopathy on its own. Instead, doctors put together information from your story, examination, and any tests that are needed.

History and physical examination

Your doctor will ask about:

Where the pain, tingling, or numbness is located.
What makes the symptoms better or worse.
When they started and whether they are getting better or worse.
Other health conditions, such as diabetes or previous spine problems.

They will examine your spine, test muscle strength and reflexes, and check feeling in different areas of skin. In the neck and lower back, this can often point strongly to a particular nerve root.

In the thoracic region, the exam may look more at rib and chest wall tenderness, posture, and whether certain movements bring on the band-like pain.

Imaging tests

Imaging helps doctors see the structure of your spine and surrounding tissues.

MRI (magnetic resonance imaging) – Often the best test for discs, nerve roots, and soft tissues. It can show disc herniations, nerve compression, and many tumours or infections.
CT (computed tomography) – Gives detailed pictures of bone and is useful for seeing bony spurs or narrow canals.
X-rays – Show the general alignment and shape of the spine but do not show nerves directly.

Not everyone with radiculopathy needs an MRI or CT right away. Many people improve with conservative treatment, and imaging is used if symptoms are severe, long-lasting, or worrying.

Electrodiagnostic testing

Electrodiagnostic tests include nerve conduction studies and electromyography (EMG). These measure how well your nerves and muscles are working.

They can help to:

Confirm that a nerve root is involved rather than a more distant nerve.
Pinpoint which level of the spine is affected.
Distinguish radiculopathy from other nerve problems, such as peripheral neuropathy.

Electrodiagnostic testing can be especially useful in thoracic radiculopathy, where imaging findings and symptoms may not line up clearly, and other causes of chest or abdominal pain need to be ruled out.

8. Red flags — symptoms that need urgent assessment

Most radiculopathy is due to wear-and-tear changes or disc problems and can be managed without emergency treatment. However, some symptoms need urgent medical attention. Contact a doctor or emergency service straight away if you notice:

Sudden chest pain with shortness of breath, sweating, nausea, or a feeling of pressure or crushing – this could be a heart or lung emergency.
Sudden weakness in arms or legs, especially if it affects both sides or makes walking difficult.
Loss of control over bladder or bowel function, or numbness in the groin area (saddle anaesthesia).
Severe back or chest pain following a major fall, accident, or injury.
Fever, unexplained weight loss, or night sweats along with back or chest pain.
Rapidly worsening pain or neurological symptoms over days to weeks.

These signs do not always mean there is something serious, but they should never be ignored.

9. Treatment options

Treatment for radiculopathy depends on the cause, the level of the spine, and how severe your symptoms are. Many people improve with conservative (non-surgical) care. Surgery is usually reserved for specific situations, such as severe or worsening weakness, or when pain does not respond to other treatments.

Conservative treatments

Activity modification – Short periods of rest during flare-ups, avoiding heavy lifting or twisting, and adjusting work or daily tasks to reduce strain. Prolonged bed rest is usually not recommended.
Physiotherapy – A physiotherapist can guide you through exercises to improve posture, strengthen support muscles, and gently mobilise the spine. For thoracic radiculopathy, this may include breathing exercises and movements that open up the spaces where the nerves exit.
Pain relief medicines – Such as paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) if they are safe for you. These help reduce pain and inflammation.
Neuropathic pain medicines – Medicines that act on nerve pain, such as certain antidepressants or anti-seizure drugs, may be used if pain is persistent and nerve-like (burning, shooting).
Heat or cold – Some people find relief using heat packs or ice packs over the painful area.
Education and pacing – Understanding your condition and learning how to pace activities can reduce flare-ups and fear around movement.

Injections and other interventional options

When pain is more severe or not settling with basic measures, doctors may offer targeted injections:

Epidural steroid injections – A mixture of anti-inflammatory steroid and local anaesthetic is injected around the affected nerve root. This can reduce swelling and pain for weeks to months in some people.
Nerve root or facet joint blocks – Injections near specific joints or nerves can help both with pain and with confirming the diagnosis.

These procedures are usually done by specialists under X-ray or ultrasound guidance to improve accuracy and safety. They are not suitable for everyone and are usually combined with exercise and rehabilitation rather than used alone.

When is surgery considered?

Surgery is generally considered when:

There is significant or worsening weakness due to nerve compression.
Pain is severe and persistent despite a good trial of conservative treatment.
Imaging shows a clear, treatable cause (such as a large disc herniation or a tumour compressing a nerve root).

Types of surgery vary depending on the level and cause but may include removing part of a disc, trimming bone spurs, or removing a mass that is pressing on the nerve. Your surgeon will discuss the potential benefits and risks in detail if surgery is being considered.

10. The Pain Decoder Takeaway

Radiculopathy is a common cause of nerve-related pain from the spine, but it can be complicated and sometimes confusing. Cervical and lumbar radiculopathy are well known, but thoracic radiculopathy, with its band-like chest or abdominal pain, is easy to miss and often mimics heart or digestive problems.

If your pain follows a strip or band, is associated with tingling, numbness, or weakness, or changes with spine position, a pinched nerve root could be part of the story. That does not mean there is something seriously wrong, but it does mean your symptoms deserve a careful look.

Most people with radiculopathy improve with time, movement, and conservative care. When symptoms are persistent, puzzling, or severe, modern imaging and nerve tests can help clarify what is going on and guide more targeted treatments.

You do not need to figure this out alone. If you recognise your own symptoms in this article, consider discussing them with your GP, physiotherapist, or a spine specialist. Bring your questions and, if you can, a simple sketch or description of where the pain travels. Clear communication is often the first step towards the right diagnosis and a better plan.
