A headache in the back of your head is most often caused by muscle tension in your neck and scalp, but it can also signal issues with the cervical spine, irritated nerves, or less commonly, a blood pressure spike. The location narrows things down considerably compared to a general headache, and understanding what’s triggering yours can help you figure out whether it needs attention or just a good stretch.
Tension-Type Headaches
The most common reason for pain at the back of your head is a tension-type headache. These produce a dull, pressing sensation that can wrap from the back of your skull around to your forehead, like a tight band. Episodic tension headaches last anywhere from 30 minutes to a full week, while chronic ones can persist for hours and feel nearly constant.
Interestingly, the older explanation that these headaches come from contracted muscles in the face, neck, and scalp has largely been abandoned. Current thinking points instead to an increased sensitivity to pain in people who get them frequently. Stress, fatigue, poor sleep, and dehydration are reliable triggers, but the headache itself appears to be more about how your nervous system processes pain signals than about muscles physically clenching.
Neck Problems That Refer Pain Upward
Your cervical spine, the section of vertebrae in your neck, can generate headaches that settle squarely at the back of your head. These are called cervicogenic headaches, and they originate from a disorder in the bones, discs, or soft tissues of the neck rather than from the brain itself. The pain often starts as neck stiffness and climbs upward.
A few features help distinguish these from other headaches. Your neck’s range of motion is typically reduced, and turning or tilting your head in certain directions makes the headache noticeably worse. The headache usually develops alongside an identifiable neck problem (a disc issue, arthritis, whiplash) and improves when that problem is treated. If you spend long hours at a desk or looking at your phone, the sustained forward position of your head puts extra load on the cervical spine, making this type of headache more likely over time.
Occipital Neuralgia
If the pain feels sharp, electric, or shooting rather than dull and achy, the culprit may be occipital neuralgia. This happens when the nerves that run from the upper spine through the scalp become pinched or irritated. The sensation often starts at the base of the skull and shoots upward along one side of the head. Some people also notice tenderness or a burning feeling in the scalp.
The most common triggers are pinched nerves and tight muscles at the back of the head that physically entrap the nerve. Prior head or neck injuries, arthritis in the upper spine, and even conditions like diabetes or gout can make occipital neuralgia more likely. It can also develop after neck or scalp surgery. The episodes tend to be brief but intense, and the pain between episodes can linger as a persistent ache at the base of the skull.
Exercise-Related Headaches
Headaches that strike during or right after physical exertion often hit the back of the head. These exertional headaches happen when intense activity causes blood vessels to expand rapidly to accommodate increased blood flow. That expansion raises pressure inside the skull, producing a throbbing pain that can last anywhere from five minutes to 48 hours.
Weightlifting, running, and high-intensity interval training are common triggers, especially in hot weather or at altitude. Most people who develop exertional headaches experience them in a cluster over three to six months, then they taper off. Staying well hydrated and warming up gradually before intense exercise can reduce the frequency. If an exertional headache is the worst you’ve ever had or comes on like a lightning bolt, that warrants immediate medical evaluation to rule out a vascular cause.
High Blood Pressure
Day-to-day high blood pressure rarely causes headaches on its own. But a hypertensive crisis, where systolic pressure reaches 180 or higher and diastolic pressure hits 120 or higher, can produce a severe headache concentrated at the back of the head. This is a medical emergency when it’s accompanied by symptoms like chest pain, vision changes, or confusion, because it signals potential organ damage to the heart, brain, kidneys, or eyes.
If you have known high blood pressure and develop an unusual headache at the back of your head, checking your reading with a home monitor is a reasonable first step. A reading at or above 180/120 with any additional symptom means calling emergency services.
Stretches That Target the Right Muscles
For tension-related and posture-related headaches at the back of your head, a few specific exercises can loosen the muscles at the base of your skull and upper neck.
- Suboccipital stretch: Lie on your back with a small rolled towel placed right at the base of your skull. Gently tuck your chin until you feel a stretch where the skull meets the neck. Hold for five seconds, relax, and repeat 10 times. Do this twice a day.
- Neck retraction: While sitting or standing, pull your head straight back as if making a double chin. Keep your eyes and jaw level. Repeat 15 times, twice a day. This counteracts the forward head position from screen use.
- Lateral neck flexion: Slowly tilt your head toward one shoulder, hold for three seconds, then tilt toward the other. Repeat 10 times per side, twice a day.
These stretches work best as a daily habit rather than a one-time fix. If you’re spending most of your day at a computer, setting a reminder to do neck retractions every couple of hours can prevent tension from building to the point where it becomes a headache.
Signs That Need Prompt Attention
Most headaches at the back of the head are benign, but certain features suggest something more serious. Headache specialists use a set of red flags to sort harmless headaches from dangerous ones, and knowing a few of them can help you make better decisions about when to seek care.
A thunderclap headache, one that explodes to maximum intensity within seconds, is the most urgent. This pattern can indicate a burst or leaking blood vessel in the brain and needs emergency evaluation immediately. New headaches that begin after age 50 are more likely to have a secondary cause than headaches that started when you were younger. A headache that steadily worsens over days or weeks, rather than coming and going, is another warning sign. So is any headache paired with new neurological symptoms: weakness on one side of your body, numbness that’s unfamiliar, or sudden vision changes.
Headaches that change with position (worse when lying down, better when standing, or vice versa) or that are triggered by coughing, sneezing, or straining may point to a pressure issue inside the skull. And if you have a headache alongside fever, night sweats, or unexplained weight loss, that combination suggests a systemic process that needs investigation.
