Neck pain spreading into the arm: trapped nerve in the neck explained
Why a nerve in the neck can cause pain, pins and needles or weakness in the arm and hand, how long it usually takes to settle, and the signs that need urgent help.
A nerve in the neck can become irritated or compressed, causing pain that travels into the arm and sometimes the hand. This is known as cervical nerve root pain, or cervical radiculopathy. It usually affects one side, can be quite painful, and in most people settles over weeks to months without surgery.
When to get urgent help
Call 999 straight away if neck pain comes with any of these. They can be signs of a stroke, meningitis or another emergency.
- Sudden severe headache unlike any you have had before
- Dizziness with double vision, slurred speech, facial droop, difficulty swallowing or weakness in an arm or leg
- Neck stiffness with a high temperature, severe headache, rash or dislike of bright light
What it can feel like
- Neck pain, with pain between the shoulder blades and spreading into the arm and sometimes the hand
- Pins and needles, numbness, or a feeling of heaviness or weakness in the arm or hand
- Symptoms usually on one side
- Pain that may be worse at night or in certain neck positions
Common contributors
- A bulging disc in the neck, due to age, repetitive movement or injury
- Age-related changes where the small joints of the neck thicken and swell, narrowing the space for the nerve
- Often no single trigger is found
General self-care
These are general comfort measures many people find reasonable. They are not a treatment plan, and what suits one person may not suit another.
- Stay gently active. An NHS trust advises that prolonged rest does not help
- Support the painful arm on pillows when resting, and avoid staying in one position for long
- Gentle heat for five to ten minutes can ease pain and muscle tension
- Pace activities using a traffic-light approach: carry on when green, reduce when amber, and ease right off when red
- Take prescribed or over-the-counter pain relief as advised by your GP or pharmacist
- Speak to a healthcare professional if your pain is worse at night
When to see your GP
See your GP promptly, or call NHS 111, if you have any of the following:
- Neck pain after a significant fall, accident or blow
- Numbness, tingling or weakness spreading into the arms or hands
- Unexplained weight loss or a history of cancer with new neck pain
Consider seeing your GP if:
- There is no improvement after four to six weeks
- Your pain is severe, keeps you awake at night, or your arm is becoming weak
- Pins and needles or numbness on both sides of the hands or feet, loss of fine hand control (for example buttons or handwriting), arm or leg weakness, an unsteady walking pattern, or loss of bladder or bowel control. These can be signs of pressure on the spinal cord and need urgent medical advice
Where an osteopath fits in
There is limited good-quality research showing that hands-on treatment changes the course of nerve-related arm pain from the neck, so I do not claim that osteopathy treats it.
An NHS trust information page says about 75% of people improve within four to six weeks, and most recover within three to six months, although it can take six to twelve months to fully settle and flare-ups are common.
What an osteopath can usefully do is examine the neck, shoulder, arm and nerve function to help distinguish a neck source from carpal tunnel or shoulder problems, check for signs that need urgent medical attention, give advice on positions of comfort and graded movement, and refer on for tests or a specialist opinion if symptoms are not following the expected course. If the assessment suggests you need your GP, a physiotherapist or a specialist instead, I will tell you.
If you would like your symptoms assessed, you are welcome to book an appointment. Osteopathic care is not right for everyone, and if something needs medical attention first, I will tell you.
Common questions
How long does a trapped nerve in the neck take to heal?
According to NHS Fife, about 75% of people improve within four to six weeks, most recover within three to six months, and it can take six to twelve months to fully settle. Setbacks and flare-ups are common.
Do I need a scan for neck and arm pain?
Not usually at first. NHS Fife says diagnosis is based on your symptoms and examination, that X-rays and scans often do not show the cause unless there was a direct injury, and that an MRI is generally not needed early on and is considered if there is no improvement.
