Neck Pain: Causes, Treatment and When to Worry

What causes neck pain

The neck (cervical spine) has 7 vertebrae, cushioning discs, small facet joints, nerves exiting toward the arms, and many muscles that hold up a head weighing about 4.5 to 5.5 kg (10 to 12 lb). Problems in any of these can cause pain.

Muscle strain and posture

Neck strain is the most common cause. Long hours looking down at a phone or laptop, carrying heavy bags on one shoulder, or sudden movements overload the muscles. Pain is usually on one or both sides of the neck and in the upper shoulders, with tight, tender muscles and stiffness when turning the head.

Sleeping awkwardly ("crick in the neck")

Waking with a stiff, painful neck that will not turn to one side is common. It usually eases within a few days. A pillow that is too high, too flat, or sleeping on your front can contribute.

Wear and tear: cervical spondylosis

Cervical spondylosis is age-related wear of the discs and joints, present on X-ray in most people over 60. It often causes no symptoms, but can lead to neck stiffness and aching that is worse after inactivity or at the end of the day.

Pinched nerve (cervical radiculopathy)

A disc bulge or bony spur can press on a nerve root, causing cervical radiculopathy. Pain spreads from the neck into the shoulder blade and down one arm, often with numbness, tingling or weakness in specific fingers. Looking up or tilting the head toward the painful side often makes it worse.

Whiplash

Whiplash follows a rapid back-and-forth movement of the neck, typically in a rear-end car crash. Pain and stiffness often build over 24 to 48 hours, sometimes with headache and dizziness.

Wry neck (torticollis)

Acute torticollis causes a sudden painful spasm that holds the head tilted and turned to one side. It is common in children and young adults and usually resolves within a week.

Other causes

• Myofascial pain: tender trigger points in neck and shoulder muscles.
• Tension headaches and cervicogenic headache, where neck problems refer pain to the head.
• Fibromyalgia: widespread pain including the neck.
• Inflammatory arthritis: rheumatoid arthritis and ankylosing spondylitis.
• Polymyalgia rheumatica: stiffness of the neck, shoulders and hips in people over 50.
• Swollen lymph glands from throat infections.

Serious but rare causes

• Meningitis: stiff neck with fever and headache.
• Spinal cord compression (cervical myelopathy): clumsy hands, poor balance and brisk reflexes.
• Fractures: after trauma, or minor falls in people with osteoporosis.
• Infections: of the spine or deep neck tissues.
• Tumors: spine metastases cause persistent night pain.
• Artery tears (dissection): neck pain and headache with stroke-like symptoms.
• Heart attack: pain spreading into the neck or jaw with chest symptoms.

Neck pain by symptom pattern

How doctors assess neck pain

A doctor asks how the pain started, where it spreads, what makes it better or worse, and about arm symptoms, injuries, fever, weight loss and other illnesses. They examine posture, neck movement, tender spots, arm strength, sensation and reflexes, and walking.

Most neck pain does not need imaging. X-rays, MRI or CT are used for red flags, significant injury, nerve or spinal cord symptoms, or pain lasting more than 6 weeks despite treatment. Nerve conduction studies help when it is unclear whether arm symptoms come from the neck or a nerve at the elbow or wrist.

Neck pain relief and treatment

Self-care

• Keep moving gently. Rest for a day or two at most; prolonged immobility and soft collars slow recovery.
• Heat or cold: a warm shower or heat pack relaxes muscles; an ice pack wrapped in a cloth can ease a fresh strain. Use for 15 to 20 minutes at a time.
• Pain relievers: acetaminophen (paracetamol), ibuprofen or naproxen, or a topical NSAID gel. Follow the label dose. Avoid NSAIDs if you have kidney disease, stomach ulcers or take blood thinners, unless your doctor agrees.
• Gentle stretches: slowly turn the head side to side, tilt ear to shoulder, and tuck the chin in, holding each for a few seconds, several times a day.
• Fix your setup: screen at eye level, chair supporting the lower back, phone raised instead of looking down, and breaks every 30 to 45 minutes.
• Sleep support: one supportive pillow that keeps your neck in line with your spine.

Medical treatment

• Physical therapy: exercises to strengthen and stretch neck and upper back muscles, manual therapy, and posture training. This is the most effective treatment for persistent pain.
• Prescription medicines: short courses of muscle relaxants, or nerve pain medicines for radiculopathy.
• Injections: epidural steroid or facet joint injections for some persistent pain.
• Surgery: for spinal cord compression, progressive weakness, or severe nerve pain that does not improve after several months.

Preventing neck pain

• Keep screens at eye level and take regular movement breaks.
• Strengthen your upper back and shoulders.
• Carry bags across the body or use a backpack with both straps.
• Avoid sleeping on your front.
• Stay active: regular exercise reduces the risk of recurrence.

Frequently asked questions

When should I worry about neck pain?

Get emergency help for a stiff neck with fever and headache, neck pain after a serious injury, or neck pain with stroke-like or heart attack symptoms. See a doctor soon for arm weakness, clumsy hands, trouble walking, weight loss, night pain or pain lasting over 6 weeks.

How long does neck pain take to go away?

Most neck pain from strain or sleeping awkwardly improves within a few days to 2 weeks. Pain from a pinched nerve often takes 6 to 12 weeks. If pain lasts more than 6 weeks, or keeps returning, a physical therapist or doctor can help.

Can neck pain cause pain in the arm?

Yes. A pinched nerve in the neck can cause pain, numbness, tingling or weakness down one arm into the hand. A large, hard lump in the upper arm is not explained by a neck problem, though, and should be examined separately by a doctor.

What is the best sleeping position for neck pain?

Sleeping on your back or side with one supportive pillow that keeps your neck level with your spine is best. Avoid sleeping on your front, which twists the neck, and avoid stacking several pillows.

Can neck pain cause headaches?

Yes. Tight neck muscles and problems in the upper neck joints can cause headaches at the back of the head that spread forward, called cervicogenic headaches. Tension headaches also often come with neck tightness. Treating the neck often improves these headaches.
