Cervicobrachialgia or cervical radiculopathy

What is cervicobrachialgia or cervical radiculopathy?

Cervicobrachialgia refers to neck pain that radiates into the arm; cervical radiculopathy refers to damage to a nerve root in the neck. This pain may be accompanied by numbness, tingling, or weakness in the arm. Neck pain that radiates into the arm may have a neurological cause, but this must be evaluated.

What is the difference between cervicobrachialgia and radiculopathy?

Cervicobrachialgia describes the path of the pain, while radiculopathy describes a problem with the functioning of a nerve root. A nerve root is the part of the nerve that exits the spinal cord, inside the spinal column.

Radiculopathy refers to a condition in which a nerve root in the neck is not functioning properly. A physical exam may reveal weakness, loss of sensation, or changes in reflexes. The pain may radiate to the arm, with or without neck pain.

The term cervicobrachialgia describes the symptoms (neck pain that radiates into the arm) without necessarily confirming that a nerve is compressed.

These terms can be used together, but arm pain alone does not prove that a nerve is compressed. The examination helps distinguish nerve damage from pain originating in other structures, such as joints or muscles.

What are the symptoms of cervicobrachialgia?

Cervicobrachialgia causes neck pain that radiates down the arm, often accompanied by numbness, tingling, sensations of electric shocks, or weakness in the arm.

The clinical presentation varies from person to person. Often, but not always, you will feel pain or stiffness in your neck, shoulder blade area, or shoulder. The pain also radiates into one or both arms and can appear in different forms.

Common symptoms in the arm

Certain neck or arm movements can trigger symptoms when nerve tissue is sensitive. An increase in pain does not necessarily indicate a lesion. However, new or worsening weakness requires prompt evaluation.

Other possible symptoms

Some people may also experience:

• A loss of sensation in the arm or certain fingers
• A loss of strength in the arm
• A feeling of a "dead arm" or a very heavy arm

These symptoms may be associated with nerve damage, but they are not sufficient to confirm it. Any recent loss of strength or sensation should be evaluated immediately. If the loss is significant or is progressing rapidly, seek urgent medical evaluation.

Serious symptoms to watch for (red flags)

However, certain signs and symptoms should prompt you to seek immediate medical attention at an emergency room or with a doctor:

• Severe weakness or paralysis in one or both arms
• Significant or complete loss of sensation in one or both arms
• Recent Loss of Balance While Walking
• New difficulty coordinating arm or hand movements
• New difficulties with bladder or bowel control
• Loss of sensation in the genital area

If you experience any of these symptoms, seek immediate medical attention. These situations are rare but require urgent medical evaluation.

What causes cervicobrachialgia?

A herniated disc or changes related to osteoarthritis can irritate a nerve root in the neck and cause pain in the arm. Other types of pain originating in the muscles or joints of the neck can also radiate down into the arm. The nerves and the nervous system play a role in processing information from these tissues. In some people, the circuits in the spinal cord and brain become more responsive—a condition known as central sensitization. This increased sensitivity can contribute to pain; however, it is not present in all people with cervicobrachialgia.¹

Main causes

Common causes of cervical radiculopathy include a herniated disc and changes in the discs or joints associated with osteoarthritis.²Cervical stenosis is a narrowing of a passageway in the neck. This can affect the passageway for a nerve root or the canal containing the spinal cord. Pain and stiffness alone are not sufficient to diagnose this condition.

When a herniated disc is the cause, part of the disc’s contents pushes against or through its outer layer and may irritate or compress a nerve root. Our guide to cervical herniated discs explains this condition in detail.

Unusual activity may precede the symptoms, such as straining to lift a heavy object. However, many people do not report any specific exertion or injury prior to the onset of symptoms.

Frequent triggers

Symptoms may begin gradually or suddenly. They may sometimes appear after:

• Significant exertion (lifting a heavy load)
• A neck or head injury (car accident, fall, impact)
• A sudden, awkward neck movement

After a whiplash injury, any pain that develops in the arm or new numbness should be evaluated. These symptoms should not automatically be attributed to the normal healing process of the neck.

How is cervicobrachialgia diagnosed?

The healthcare professional will evaluate cervicobrachialgia based on your symptom history and an examination of your neck, arm, and nerve function. Your physical therapist or doctor will ask you questions about:

• When the Pain Began
• What movements trigger the pain
• Where exactly you feel the symptoms in your arm
• If you have weakness or numbness

The clinical examination includes

The physical assessment will involve examining:

Additional tests

An X-ray mainly shows the bones. Magnetic resonance imaging (MRI) can show the intervertebral discs, nerve roots, and spinal cord. It may be recommended if there are concerning signs or when symptoms persist despite initial treatment, often after four to six weeks. An electromyogram (EMG) measures the electrical activity of the muscles and can help distinguish between various causes of neurological symptoms.³

Diagnosis usually begins with a clinical examination. Additional tests are performed to answer a specific question, such as confirming compression or investigating another cause. Their usefulness depends on the symptoms and the results of the examination.⁴

When to consult a physiotherapist?

A physical therapy evaluation can be helpful for neck pain that radiates into the arm and limits daily activities, provided there are no signs of a medical emergency. New-onset weakness or loss of sensation warrants prompt evaluation. The serious signs described above require immediate medical attention.

If a doctor has ruled out an urgent cause, the physical therapist can continue the evaluation and organize rehabilitation. However, any significant new worsening of symptoms must be reevaluated by a doctor.

In private practice in Quebec, a physical therapy consultation does not require a doctor’s prescription. However, this does not replace an urgent medical evaluation when warning signs are present.

Physical therapy for neck pain offers exercises and treatments tailored to neck and arm pain. The treatment aims to relieve symptoms and restore movement in your neck and arm.

How is cervicobrachialgia treated in physical therapy?

Physical therapy treats cervicobrachialgia with tailored exercises, manual techniques, and advice on how to manage daily activities.

Your physical therapist will identify the movements, activities, and other factors associated with your symptoms. The examination also determines whether a nerve disorder is causing your difficulties.

Elements Assessed by the Physiotherapist

Personalized Treatment Plan

Based on the assessment results, your physiotherapist will:

• May offer joint mobilization, guided joint movements using the hands, and, if appropriate, nerve mobilization to improve movement and try to relieve symptoms
• Will give you specific exercises to do at home to improve your movement and abilities
• Will teach you how to balance your daily activities to support a gradual return to normal activities
• Will give you advice on your posture and movement habits

Nerve mobilization techniques use arm and neck movements that stimulate nerve tissue. The physical therapist tailors these movements to your symptoms. A 2023 review reported relief and improved function in several comparisons. A 2024 review, which focused on symptoms persisting for more than three months, found primarily an improvement in mobility when these techniques were added to standard care, with no clear benefit regarding pain. A 2025 systematic review also reports potential benefits but rates the certainty of the results as low to very low. These techniques can therefore be tried depending on your situation, though there is no guarantee that they will release a pinched nerve or provide relief for everyone.^{5, 6, 7}

Appropriate exercises can improve neck and arm function and help you return to your activities. The program may include strength training and mobility exercises. The progression depends on your ability and how you respond.⁸

What to Do at Home to Relieve Cervicobrachialgia?

Gentle neck movements, adjusting your activities, and comfortable arm support can help manage cervicobrachialgia at home. Temporarily limit movements that cause severe pain and change positions regularly.

Temporarily stop movements that cause a lot of pain. Gradually resume them later, as the pain decreases.

Non-surgical treatments are generally offered first, unless a serious condition requires a different course of treatment.⁴ Rapid neck manipulations require a prior evaluation and a discussion of the benefits, risks, and other options. Serious complications have been reported following these^{manipulations. ⁹, ¹⁰} Clinical trials cannot rule out rare serious complications, and isolated case reports are insufficient to estimate their frequency. Slower mobilization techniques and exercises are among the other options.

Practical Tips for Home

Gently move your neck, staying within a range of motion that feels comfortable. Movement helps maintain mobility. Stop any movement that significantly increases symptoms in your arm. Have your exercise program reviewed if the symptoms persist. Any new weakness requires prompt evaluation.

Support your arm if that helps. Try a comfortable position that doesn't strain your neck. Here are a few options:

• With a cushion under the armpit
• With the armrests of a chair or sofa
• By putting your hand in your pants pocket while standing

Limit the amount of time you spend in the same position (at the computer, watching TV, reading). Get up regularly for a few minutes to move your neck and shoulders.

Support your neck comfortably while sleeping with a pillow that fills the hollow of your neck. No sleeping position is inherently good or bad: if you wake up stiff or in more pain, try sleeping in a position other than on your stomach for a few nights and see what works best for you right now.

What else should you know about cervicobrachialgia?

Cervical radiculopathy often improves over time with non-surgical treatment, but the duration of recovery varies, and symptoms may return. The course of the condition depends, in particular, on the cause and the extent of nerve damage.

A study conducted in Rochester, United States, between 1976 and 1990 estimated approximately 83 new cases of cervical radiculopathy per 100,000 people per year.¹¹ In this population, the incidence was highest among those aged 50 to 54, but younger and older individuals were also affected.

In people whose radiculopathy stems from a cervical disc herniation, most of the improvement often occurs within the first four to six months. In the cited review, approximately 83% had made a full recovery between 24 and 36 months.¹² Non-surgical treatments, including physical therapy, are often the first step in management.⁴

The C7 and C6 nerve roots were the most commonly affected in this study. The letters and numbers indicate their exit levels in the neck.¹¹ Involvement of the C6 nerve root can cause symptoms in the thumb and index finger; involvement of the C7 nerve root can affect the middle finger. These pathways overlap and vary. The examination therefore also assesses muscle strength, reflexes, and sensation. Identifying the affected nerve helps guide treatment.

Surgery is not routinely performed. In the absence of signs of an emergency or significant, progressive weakness, a physical therapy program may be tried before considering surgery. In the randomized controlled trial, surgery led to faster improvements in certain outcomes during the first year, but the difference compared with physical therapy alone narrowed after two years, and objective measures of physical function did not differ significantly between the groups.^{13, 14}

Surgery may provide relief more quickly in the first few months. In an earlier trial involving radiculopathy associated with osteoarthritis, differences in pain and sensitivity had diminished after about sixteen months. A 2025 trial distinguished between herniated discs and osteoarthritis: at twelve months, it observed an average benefit from surgery for neck-related symptoms in the group with herniated discs, but no clear difference in the group with osteoarthritis. This average benefit remained below the threshold for significant improvement established by the study. These results do not guarantee that all treatments are equally effective for every individual.^{15, 16} Many people improve without surgery. However, persistent pain or a decline in strength warrants a reassessment of the care plan.
