Yes, a neck problem can cause a headache. When it does, it is called a cervicogenic headache, meaning a headache whose source sits in the neck rather than the head. The pain usually starts at the base of the skull on one side and spreads forward over the head, sometimes settling behind the eye on that same side. It often feels like a deep, steady ache rather than a throb.
Why a neck problem can be felt as head pain
The top three nerve roots in your neck feed into a relay station in the brainstem. The nerve that supplies your face, forehead and scalp, called the trigeminal nerve, feeds into the same relay station. Because those signals share one pathway, the brain cannot always tell which one it is hearing from.
So an irritated joint or muscle in your upper neck can produce a signal your brain reads as pain over the eye or across the forehead. The pain is real. It is simply reported from the wrong address.
That is why treating the head alone often fails when headaches keep coming back.
How to recognise a headache that starts in the neck
Cervicogenic headache has a fairly consistent pattern:
- It is usually on one side, and almost always the same side every time
- It begins in the neck or at the base of the skull, then spreads forward
- Neck movement or a held posture makes it worse
- Turning your head feels stiff or restricted on the painful side
- Pressing the base of the skull on that side often reproduces the pain
- There is usually no nausea and no strong sensitivity to light or sound
That last point matters. Nausea, light sensitivity and a pulsing quality point more towards migraine. A headache that switches sides is also less likely to come from the neck.
Cervicogenic headache vs migraine vs tension headache
People often search for headache location meaning, hoping the spot will name the cause. Location helps, but the full pattern tells you more.
| Cervicogenic | Migraine | Tension-type | |
|---|---|---|---|
| Which side | One side, same side each time | Usually one side, can switch | Both sides |
| Where it starts | Neck or base of skull | Around or behind one eye | Band around the head |
| Triggers | Neck movement, sustained posture | Sleep changes, hormones, stress | Stress, fatigue, screen time |
| Comes with | Neck stiffness, reduced movement | Nausea, light and sound sensitivity, aura | Mild tightness, little else |
| How long | Hours to days, often a constant background ache | Four to 72 hours, then clears | Thirty minutes to several days |
These patterns overlap, and some people have more than one headache type at once. That is one reason an assessment helps.
What a back of head headache can mean
Pain fixed at the back of the head has two usual explanations.
The first is muscular: a dull, spread-out ache across the base of the skull and upper neck that eases with heat or gentle movement.
The second is occipital neuralgia, where the occipital nerves running from the upper neck up the back of the scalp become irritated. That pain is sharp, shooting or electric, it travels up the back of the head in bursts, and the scalp can become so tender that brushing your hair hurts.
Sharp and electric points to a nerve. Dull and spread out points to muscle, and telling them apart changes the treatment.
Why do I wake up with a headache?
Morning headaches usually come down to what happened during the night.
Sleeping position and pillow height are the most common culprits. A pillow that pushes your head too far forward, or lets it drop too far back, holds the upper neck at an end range all night. Neck pain after sleeping, plus a headache that fades an hour or two after you get up, fits that picture.
Jaw clenching during sleep is another cause. It loads the jaw joint and muscles that share a nerve pathway with the upper neck.
A third cause deserves attention. Sleep disorders, including sleep apnea, often show up as morning headaches. If you snore heavily, wake unrefreshed, or have been told you stop breathing at night, raise it with your family doctor.
What is actually going on in the neck
Most cervicogenic headaches trace back to the small facet joints at the top of the neck, the paired joints that let you nod and rotate your head. They can become painful through everyday wear, age-related degenerative change, or an old whiplash injury, sometimes years later.
Prolonged desk and phone posture adds to it, because holding the head forward keeps those joints under constant load. Nerve irritation in the neck can also send symptoms into the arm, a separate pattern covered on our page about neck pain and cervical radiculopathy.
How neck-related headaches are assessed and treated
Treatment works best as a ladder, starting at the bottom.
Posture and workstation. Raise your screen to eye level, support your forearms, and change position often. Check your pillow height so your head stays in line with your spine.
Physiotherapy. The useful kind targets the deep neck flexors, the small stabilising muscles at the front of the neck, along with hands-on treatment of the upper neck joints.
Interventional pain care. When those steps are not enough, a pain physician can work on the source directly.
The key idea is the diagnostic block. A small amount of local anaesthetic is placed next to the medial branch nerves supplying one facet joint, using image guidance. If your usual headache settles for the expected duration, that joint is confirmed as the source. If nothing changes, it is not, and you have been spared a treatment that would not have helped.
Once blocks confirm the source, radiofrequency ablation can interrupt those small nerves for a longer period, and many patients find their headache frequency drops. For occipital neuralgia, occipital nerve blocks target the irritated nerve at the back of the head. Where the diagnosis turns out to be chronic migraine instead, Botox for migraines is a separate and well-established option.
Headache warning signs that need urgent care
Get emergency care the same day if you have:
- The worst headache of your life, or one that peaks within seconds
- Headache with fever and a stiff neck
- Headache after a blow to the head
- Headache with new weakness, numbness, slurred speech, confusion or vision loss
- New scalp tenderness with jaw pain when chewing, if you are over 50 (this can indicate giant cell arteritis, which needs same-day assessment)
- A headache pattern that suddenly changes in nature, timing or severity
These are uncommon, but each needs ruling out quickly rather than watching.
Common questions about neck pain causing headaches
Can a stiff neck really cause a headache behind the eye?
Yes. Signals from the upper neck and the face converge on the same relay point in the brainstem, so the brain can misplace neck pain as pain behind the eye. The eye itself is usually normal on examination, which is a clue that the source lies lower down.
How do I know if it is a migraine or my neck?
Migraine tends to bring nausea, sensitivity to light and sound, and a throbbing quality, and it can switch sides. A neck-driven headache stays on the same side, starts at the base of the skull, worsens with neck movement, and comes with restricted head turning.
Will an X-ray or MRI show why my neck causes headaches?
Imaging can show degenerative change or old injury, but many people have those findings without headaches. Diagnosis rests mainly on your pattern and a physical examination. A diagnostic block is often more informative than a scan for confirming which joint is responsible.
Does the pillow really matter?
It can matter a great deal for morning headaches. The aim is neutral alignment, so your head is neither pushed forward nor tipped back. Side sleepers usually need a thicker pillow than back sleepers. A clear difference within two weeks is meaningful information.

Talk to a pain physician about your headaches
If your headaches keep returning and your neck is involved, an assessment can identify whether the neck is the source and which treatments are worth trying. Our physicians in North Toronto assess neck-related headaches and provide image-guided treatment where appropriate.
Most services are covered by OHIP with a physician referral, and you can also refer yourself directly. If your family doctor prefers to send the paperwork, they can use our physician referral form.
