Why a Stiff Neck Can Give You a Headache
"Whenever the back of my neck gets stiff, I get a headache." Here is that question played out as a scene, in the order the conversation actually goes during a consultation.
Sungjong Park, D.C. · October 2026 · Reading time 5 minThis is a fictional consultation created for illustration. It does not reflect any real person's consultation and is not a substitute for individual diagnosis or treatment.
When a lecture ends and questions open up, one comes up almost every time: "Whenever the back of my neck gets stiff, I get a headache. Is it my neck?" It's a short question with a long answer. So this time, instead of explaining, I've written it as a scene. Picture an office worker in their 30s who spends ten hours a day in front of a monitor.
What we ask before we talk about the neck
When a headache comes up, the questions come before anyone looks at the neck. First we need to rule out headaches that have nothing to do with the neck, or headaches where the neck should not be touched at all. Medicine collects these warning signs in a list known by its acronym, SNNOOP10. It covers things like fever, a history of cancer, neurological symptoms, sudden onset, a first headache after age 50, a change in pattern, headaches that change with posture or coughing, pregnancy, trauma, and overuse of pain medication.
The list isn't meant to scare anyone. According to the source that introduced these criteria, secondary headaches, meaning those caused by another condition, make up about 2% of headaches seen in primary care. In emergency departments and specialist centers, where more serious cases gather, that rises to about 20%. Most headaches are nothing to worry about, but we check every time so the rare case isn't missed.
ClientLately, by the time I leave work, the back of my neck is stiff as a rock, and the back of my head feels heavy too.
PractitionerWe'll get to your neck in a minute. First, a few questions. Do you have a fever, or feel like you're coming down with something?
ClientNo, nothing like that.
PractitionerHas a headache ever hit suddenly, like a hammer, and peaked within minutes? Any weakness in your arms or legs, slurred speech, or strange vision?
ClientNo, never. It just slowly gets heavier.
PractitionerHave you hit your head recently? Does the headache get worse when you cough or strain? And how many days a month do you take painkillers?
ClientI haven't hit my head. I take something once or twice a week.
PractitionerGood. Just one more. Has the headache changed a lot from how it used to be, or does it feel like it's getting steadily worse?
ClientIt's been about the same for years. Worse when I'm busy.
Squeezing headaches, one-sided headaches
Only after confirming there are no warning signs do we ask what the headache is like. In the International Headache Society's classification (ICHD-3), two types come up most often in connection with the neck.
The first is tension-type headache, which is very common. It feels like a band squeezing or pressing on both sides of the head, and the pain is mild to moderate. It usually doesn't get worse with walking or climbing stairs, and the muscles around the head and neck are often tender to the touch.
The second is cervicogenic headache. This headache starts from a problem in the structures of the neck, such as the vertebrae, the nearby joints, discs, or muscles. It usually favors one side, moving the head or pressing on the neck muscles reproduces the usual headache, and it may spread from the back of the head toward the front. Even so, these features alone don't settle the diagnosis. ICHD-3 asks clinicians to weigh several kinds of evidence together, such as whether neck movement is reduced and whether the neck problem and the headache started and improved together. Changes seen on neck imaging are also common in people without headaches, so they can't be taken as the cause on their own.
PractitionerWhen it hurts, does it feel like both sides of your head are being squeezed, or is it just one side?
ClientBoth sides. Like wearing a hat that's too tight. But the back of my neck hurts too, so I figured it's a neck problem.
PractitionerNeck pain alongside a headache doesn't always mean a problem with the neck bones. The way you describe it is something we often hear with tension-type headache. We can't tell which it is from talking alone, though. That takes an assessment.
Why the back of the neck and head?
Pain signals from around the upper neck vertebrae (C1 to C3) meet, at the same point in the brainstem, the signals from the nerve that carries sensation from the face and head. That's why neck discomfort can feel like a headache.
Just below the back of the skull sit small muscles called the suboccipital muscles. They control fine head movements and posture. When you spend long hours looking at a screen with your head pushed forward, these muscles never get to rest.
In forward head posture, where the head sits in front of the shoulders, a common pattern is seen: the muscles at the back of the neck and the chest become short and tight, while the deep muscles at the front of the neck and the lower trapezius in the back become weak. Tight knots within muscles can also send pain to distant areas, such as the head. Interestingly, ICHD-3 explains that headaches arising from knotted neck muscles like this are better classified as tension-type headache than as cervicogenic headache. It also notes that the two often overlap, which makes them hard to tell apart.
ClientSo what should I do about my neck?
PractitionerWhat I can offer right now is an explanation and the direction an assessment would take. From a chiropractic perspective, we'd listen to when your headaches come, how often, and what they feel like, look at how you sit and stand, check for tenderness in the neck and shoulder muscles, see in which directions movement is reduced when you bend your head forward, tilt it back, and turn it, and check whether that brings on your usual headache.
ClientDo I need an X-ray?
PractitionerWhether imaging is needed is for a doctor to decide. And if even one of the warning signs I mentioned shows up, set the neck aside and see a neurologist first.
Things worth trying at home
Here are a few things worth trying at home, with two conditions: no warning signs, and no pain when you do them. If your headache or dizziness gets worse while you're doing any of these, stop right away.
- Warm compress: Place a warm towel on the back of your neck for about 10 to 15 minutes.
- Lying suboccipital release: Lie on your back and rest the hollow just below the back of your skull on your fingers or a soft ball. Don't tilt your head back. Breathe easily for 1 to 2 minutes.
- Chin tucks: Sit upright looking straight ahead and gently draw your chin back, as if making a double chin. Hold for 5 seconds. This is not a nodding-down movement. About 10 reps.
- Screen height: Set the top of your monitor near eye level, and use a stand for your laptop.
- Get up from your seat: Every 30 to 60 minutes, stand up, roll your shoulders, and change position.
See a doctor first if…
- A severe headache that comes on suddenly and peaks within minutes (thunderclap headache)
- Neurological symptoms such as weakness in the arms or legs, slurred speech, vision changes, or reduced consciousness
- A headache that worsens with fever, or comes with fever or other whole-body symptoms
- A first headache after age 50
- A headache that began after a head injury
- A headache that is steadily worsening or has changed markedly from its usual pattern
- A headache triggered by coughing, sneezing, or exercise, or one that changes greatly with posture
- A headache in someone with a history of cancer, a weakened immune system, or during pregnancy or shortly after giving birth
- A headache that comes with taking painkillers frequently, or with a newly started medication
If any of the above applies, hold off on self-care or anything that puts force on the neck, and see a specialist such as a neurologist first. If you have a sudden, severe headache or neurological symptoms, go to the emergency room without delay.
Next time your neck stiffens and your head gets heavy, ask yourself one thing before you rub your neck: is this headache the same as usual?
