Pain at the back of the neck most often comes from tired or strained muscles and irritated small joints between the neck bones (facet joints). It usually follows long hours looking down at a screen, an awkward night’s sleep or a sudden movement. Most episodes ease over a few days to a few weeks.
Where exactly it hurts narrows the likely causes. A dull ache across the back of the neck points somewhere different from a sharp pain on one side, a headache at the base of the skull or tingling down the arm. This page goes spot by spot. It narrows things down. It does not diagnose. A physical therapist or doctor who examines you can do that.
First: the signs that skip the line
- Call your local emergency number now: neck pain with a sudden, severe headache unlike any before, or with double vision, slurred speech, a drooping face, trouble swallowing or loss of balance. Also call after a fall, crash or blow to the head with severe neck pain, or with new loss of bladder or bowel control.
- Go to the emergency department today: fever with a stiff neck and headache, especially with sensitivity to light, confusion or a rash.
- See a doctor within days: arm weakness that is getting worse, clumsy hands (dropping things, trouble with buttons) or unsteady walking.
- See a doctor soon: neck pain that wakes you whatever position you lie in, or that comes with unexplained weight loss, a history of cancer or a weakened immune system.
Back of the neck
A dull ache or tight band across the back of the neck, sometimes spreading to both sides. Turning or looking up feels stiff. It tends to build through the workday and after long stretches with the head forward over a laptop or phone. Poor sleep and stress often make it louder.
- Muscle-related neck pain (neck strain): a broad ache, tender to press, worse after holding one position and easier once you move. The most common cause; usually settles within a few days to a few weeks.
- Facet joint irritation: sharper, often a little to one side of the center line. It catches at the end of turning or tilting the head back.
- Disc-related neck pain: a deeper, central ache, often worse after long periods looking down. It can spread to the shoulder blade, and into the arm if a nerve is involved.
- Age-related wear (cervical spondylosis): common from middle age and often painless. When it hurts, stiffness is usually worst first thing in the morning and loosens through the day.
Side of the neck
Often sharper and more specific, running from behind the ear toward the top of the shoulder. Checking your blind spot while driving, holding a phone between ear and shoulder, or sleeping with the head bent sideways tends to set it off.
- Acute wry neck (acute torticollis): you wake with the head stuck slightly turned or tilted, and straightening it hurts. It often eases within a few days and usually clears within one to two weeks.
- One-sided facet joint irritation: pain at a point beside the spine, worse turning or tilting toward that side.
- Muscle strain along the side of the neck: the levator scapulae and scalene muscles feel tight and tender. More of a pull, worse when you stretch away from the sore side.
- A lump or swollen gland: a tender lump at the side of the neck during a sore throat or cold usually comes from a lymph node. A lump lasting more than about two to three weeks, or one that is hard and painless, needs a doctor to look at it.
Base of the skull and headache from the neck
The ache sits where the neck meets the skull, often with a headache. Long screen sessions, short nights and jaw clenching tend to bring it on.
- Headache from the neck (cervicogenic headache): usually one-sided. It starts in the neck and spreads toward the forehead or behind the eye. Neck movements or held positions bring it on, and the neck is often stiff on the same side.
- Tension-type headache: a pressing band around both sides of the head, often with tight muscles at the base of the skull. Usually mild to moderate, and walking does not make it worse.
- Occipital nerve irritation (occipital neuralgia): brief, sharp, electric pain from the base of the skull up over the back of the scalp, with a tender spot just below the skull.
- Migraine: neck pain often comes before or during an attack. Throbbing, nausea, sensitivity to light or sound, and attacks lasting hours to days point toward migraine.
Neck pain spreading to the top of the shoulder
The ache slopes from the side of the neck over the top of the shoulder, sometimes into the shoulder blade. A heavy bag on one shoulder, shrugging while you type and stress tend to feed it.
- Upper trapezius tension: the large muscle across the top of the shoulder is tight, with tender knots. An ache rather than sharp; movement and warmth usually ease it.
- Referred pain from the lower neck: joints and discs low in the neck can send pain here even when the neck barely hurts. It changes when you move your neck.
- A shoulder problem instead: the AC joint on top of the shoulder hurts at one fingertip-sized point, worse reaching across your body. Rotator cuff pain sits more on the outer upper arm and comes on when you lift the arm.
A rough guide: if turning or tilting your head changes the pain, the neck is the more likely source. If lifting or reaching changes it, the shoulder is more likely. Some people have both.
Where it hurts is a clue. What changes it, and what comes with it, tells you more.
Neck pain traveling down the arm
Pain, tingling or numbness can spread from the neck or shoulder blade down the arm. Looking up, turning or tilting toward the sore side, and sometimes coughing or sneezing, tend to make it worse.
- Pinched nerve in the neck (cervical radiculopathy): a nerve root is irritated where it leaves the spine, often by a disc bulge or a narrowed opening. Pain follows a line down the arm, may pass the elbow and can bring tingling in particular fingers. Some people find resting the hand on top of the head eases it. Many improve over several weeks to a few months without surgery.
- Referred pain from the neck: a deep, vague ache into the shoulder and upper arm, usually above the elbow and without pins and needles.
- Pressure on the spinal cord (cervical myelopathy): less common. Clumsy hands, numbness in both hands, changes in handwriting and unsteady walking. Neck pain may be mild or absent. This needs a doctor within days.
- Nerve pressure near the collarbone (thoracic outlet syndrome): heaviness or tingling in the arm, often toward the little finger, worse with the arms overhead or carrying heavy bags.
Tingling that stays in the hand and is worst at night or when gripping can come from the elbow, wrist or hand rather than the neck.
Where else this could be coming from
- Upper back: a stiff upper back leaves the neck doing more of the turning. Pain between the shoulder blades often travels with neck pain.
- Jaw: clenching and jaw joint problems can send pain to the side of the head and upper neck, often with clicking or soreness when chewing.
- Heart: neck, jaw or left shoulder pain that comes on with exertion and eases with rest, especially with chest pressure or breathlessness, needs emergency care.
Still not sure
Get assessed by a physical therapist or doctor if your neck pain is not clearly easing after about one to two weeks, if it keeps coming back, or straight away for any of the signs at the top of this page. Arm symptoms that are spreading or getting stronger deserve a check sooner.
Before you are seen, note where the pain started and where it reaches now, what eases and worsens it, whether head or arm movement changes it, and any tingling or weakness, including which fingers.

Most neck pain settles with time and gradual movement, and the spot it lives in tells you which questions to ask.
