A headache concentrated at the back of your head usually traces to one of a handful of causes, the most common being tension in the muscles of your neck and scalp. But the location alone does not pin down a single diagnosis. Pain in that region can arise from problems in the upper cervical spine, irritation of the occipital nerves, poor posture, high blood pressure, or, less commonly, serious vascular events that need emergency attention. The cause matters because some back-of-the-head headaches respond to a posture fix or over-the-counter painkillers, while others signal something you should not ignore.
Tension-Type Headache and Tight Muscles
The single most common explanation for a dull, pressing ache at the back of the skull is a tension-type headache. Unlike migraine, which tends to throb on one side and brings nausea or light sensitivity, a tension-type headache feels like a band squeezing around your head, and the pain often settles into the base of the skull and the muscles alongside it. Research consistently finds that people with tension-type headache have significantly more tenderness in the muscles around the skull, along with a higher number of myofascial trigger points, compared to people without headache.1PubMed. The role of muscles in tension-type headache Trigger points are essentially small, hyperirritable knots in muscle tissue that, when pressed or contracted, refer pain to a distant area. In the suboccipital muscles at the very top of your neck, these knots frequently send pain upward into the back and top of the head.
Stress, fatigue, jaw clenching, and poor sleep can all set off a tension-type headache. The pain is annoying but not dangerous, and for most people it resolves with rest, gentle stretching, or a standard painkiller. When it becomes chronic, meaning it occurs 15 or more days per month, the trigger-point component tends to be even more pronounced, which is why some people get relief from massage or physical therapy targeting those knotted muscles.
When Your Neck Is the Real Problem
If the headache at the back of your head seems connected to neck movement or stiffness, the pain may actually originate in the cervical spine rather than in the head itself. This pattern is called cervicogenic headache. It starts in the structures of the upper neck, including joints, discs, and muscles innervated by the first three cervical spinal nerves, and gets referred upward into the skull through a shared pain-relay system in the brainstem.2PubMed. Cervicogenic headache: anatomic basis and pathophysiologic mechanisms Because pain signals from the neck and pain signals from the head converge on the same relay neurons, the brain can misinterpret neck pain as head pain. This referral can extend all the way to the forehead or behind the eye, even though nothing is wrong with those areas.3PubMed. Cervicogenic headache: evidence that the neck is a pain generator
Cervicogenic headache typically starts on one side, worsens with certain neck positions, and may be accompanied by reduced range of motion. People with prior whiplash injuries, desk-bound work habits, or degenerative changes in the upper cervical joints are especially prone. Treatment directed at the cervical pain source, rather than at the head, tends to be more effective here. A systematic review and meta-analysis found moderate-quality evidence that spinal manipulation reduced headache intensity and frequency in these patients when compared with sham treatments.4PubMed Central.

Forward Head Posture and Screen Time
You have probably heard that hunching over a phone or laptop causes headaches, and there is real evidence behind the claim. When your head juts forward relative to your shoulders, the suboccipital muscles at the base of the skull work harder to keep your eyes level with the horizon. That sustained contraction can generate trigger points in those muscles. One study found that people with chronic tension-type headache had significantly more forward head posture than headache-free controls, and the degree of forward-head positioning correlated positively with headache frequency and duration.5PubMed. Trigger points in the suboccipital muscles and forward head posture in tension-type headache
The encouraging flip side is that correcting posture can reduce the headaches. A controlled trial on tension-type headache patients found that improving the craniovertebral angle (a measure of how far forward the head sits) led to a meaningful decrease in headache disability scores, and that improvement held during follow-up.6PubMed Central. Impact of Cervical Sensory Feedback for Forward Head Posture on Headache Severity and Physiological Factors in Patients with Tension-type Headache: A Randomized, Single-Blind, Controlled Trial If your back-of-the-head headaches tend to worsen during long stretches at a desk and improve on weekends, posture is a strong suspect. Simple adjustments like raising your monitor to eye level, taking movement breaks, and doing chin-tuck exercises can make a genuine difference over weeks.
Occipital Neuralgia
Occipital neuralgia is a less common but more dramatic cause of pain at the back of the head. It involves irritation or injury to the greater or lesser occipital nerves, which run from the upper neck up through the scalp. Instead of the dull squeeze of a tension headache, occipital neuralgia produces sharp, shooting, or electric-shock-like jolts that typically start at the base of the skull and radiate upward along the back of the head toward the top.7PubMed. Occipital neuralgia Some people feel tenderness over the nerve path, and light touch on the scalp can be surprisingly painful.
The anatomy helps explain why this nerve is vulnerable. The greater occipital nerve, roughly four millimeters in diameter, pierces through the thick semispinalis capitis muscle near the base of the skull. In about 44 percent of people studied, the nerve is asymmetric on the two sides, and in a small percentage the nerve is split by muscle fibers, creating extra points of potential entrapment.8Plastic & Reconstructive Surgery. Anatomical Variations of the Occipital Nerves: Implications for the Treatment of Chronic Headaches Tight muscles, trauma, or even arthritis in the upper cervical spine can squeeze these nerves and set off the pain.
Diagnosis is often confirmed through a nerve block: a clinician injects a local anesthetic around the greater occipital nerve, and if the pain resolves, that strongly supports the diagnosis.9PubMed. Occipital Neuralgia and Cervicogenic Headache: Diagnosis and Management For longer-lasting relief, a randomized trial found that injecting botulinum toxin alongside the nerve block produced significantly lower pain scores at four, eight, and even 24 weeks compared to anesthetic alone.10PubMed Central.

Migraine That Settles in the Back of the Head
Migraine is most often associated with one-sided throbbing pain at the temple, but it does not always follow that script. Some people experience migraine predominantly in the occipital region. The reason ties back to convergence in the brainstem: pain signals from the meninges (the membranes covering the brain) and from the upper cervical structures share the same relay neurons in what is called the trigeminocervical complex.11PubMed. The trigeminocervical complex and migraine: current concepts and synthesis When that relay system becomes sensitized during a migraine attack, pain can spread or be referred to the back of the head, the neck, and even the shoulders. This is why some migraine sufferers report neck stiffness as one of their earliest warning signs, sometimes mistaking their migraine for a “neck problem.”
The key to recognizing migraine, regardless of location, is the accompanying features: sensitivity to light or sound, nausea, worsening with routine physical activity, and a pattern of moderate to severe episodes lasting hours to a day or two. If your back-of-the-head pain ticks those boxes, it is worth treating as migraine rather than simply taking a neck-focused approach.
High Blood Pressure and Back-of-the-Head Pain
There is a long-standing popular belief that high blood pressure causes headaches at the back of the head, and the relationship is genuine but narrower than people tend to assume. Mild or moderate hypertension is usually silent. The headache connection kicks in when blood pressure is severely elevated. In those cases, the increased vascular pressure can strain the blood vessels supplying the head and neck, generating pain that is often felt in the occipital region.12Jurnal Kesehatan Komunitas Indonesia. Progressive Muscle Relaxation to Reduce Chronic Pain in Elderly with Hypertension: A Case Study A headache that shows up alongside a blood pressure reading above roughly 180/120 warrants urgent medical attention, because it may signal a hypertensive crisis.
If you regularly experience back-of-the-head pain in the morning that fades during the day, and your blood pressure has been running high, it is worth having the two evaluated together. But do not assume that every occipital headache means high blood pressure. Most do not.
Vascular Emergencies Worth Knowing About
The vast majority of headaches at the back of the head are not dangerous. But a small number of serious vascular events can present this way, and recognizing the pattern could save your life.
A thunderclap headache, defined as severe head pain that reaches maximum intensity within seconds, is the most alarming scenario. It can signal a subarachnoid hemorrhage, which is bleeding around the brain, and the pain is frequently occipital.13The Lancet Neurology. Thunderclap headache A case report of a clinically stable young man who presented with thunderclap headache and was found to have a subarachnoid hemorrhage underscores that even patients who “look fine” after such a headache need imaging.14PubMed Central. Perimesencephalic Subarachnoid Hemorrhage After Thunderclap Headache in a Clinically Stable Patient: A Case Report Thunderclap headache can also be the first sign of cervical artery dissection, cerebral venous sinus thrombosis, or acute hypertensive crisis.
Vertebral artery dissection deserves special mention because it often presents as neck or occipital pain without obvious neurological symptoms at first, and it is frequently missed. A case described in the literature involved a 38-year-old woman with no clear risk factors whose isolated headache was only diagnosed as a vertebral artery dissection after multiple primary care visits and an urgent care visit before she finally went to the emergency room.15PubMed Central. Spontaneous Vertebral Artery Dissection: A Commonly Overlooked Cause of Headache Vertebral artery dissection tends to occur in younger patients, and it carries the risk of stroke if untreated. Additionally, strokes affecting the posterior circulation (the blood supply to the back of the brain) are more likely to be associated with headache than strokes in other areas, with one meta-analysis finding roughly twice the odds of headache in posterior circulation strokes compared to anterior ones.16PubMed Central.

Structural Conditions in the Skull and Upper Spine
Two structural conditions are worth knowing about if occipital headaches become recurrent and do not respond to the usual approaches.
The first is Chiari I malformation, where the lower part of the brain (the cerebellar tonsils) extends downward through the opening at the base of the skull. This crowds the space where cerebrospinal fluid normally flows freely, and when that flow is obstructed, coughing, straining, or bending over can spike the pressure inside the spinal canal, triggering a headache at the base of the skull.17Journal of Neurosurgery. Pathophysiology of headache associated with cough in patients with Chiari I malformation A back-of-the-head headache triggered by coughing, laughing, or bearing down is the classic presentation, and surgery to decompress the area often resolves the headaches partially or completely.18PubMed. Headache and Chiari I malformation: clinical presentation, diagnosis, and controversies in management
The second is osteoarthritis of the atlantoaxial joint, the junction between the first and second cervical vertebrae right at the top of your spine. In a study of patients with spinal degenerative disease, atlantoaxial osteoarthritis accounted for about 4 percent of cases and produced a distinctive syndrome: occipital pain, tender trigger points in the occipital region, audible or palpable crepitus when the head was rotated, and sometimes a visible head tilt.19PubMed. Atlantoaxial (C1-C2) facet joint osteoarthritis: a distinctive clinical syndrome Advanced cases can develop bone spurs that compress the nearby C2 nerve root, producing occipital neuralgia on top of the joint pain.20PubMed Central.

Giant Cell Arteritis in Older Adults
If you are over 50 and developing a new headache at the back of the head, there is one inflammatory condition that clinicians specifically screen for: giant cell arteritis, an inflammation of the blood vessel walls that typically affects the temporal arteries but can also involve the occipital arteries. A prospective study using ultrasound found that involvement of the occipital arteries in giant cell arteritis patients was a frequent finding and was sometimes the only abnormality, presenting as occipital headache, neck pain, and scalp tenderness over the back of the head.21PubMed. Giant cell arteritis of the occipital arteries–a prospective color coded duplex sonography study in 78 patients Giant cell arteritis is worth catching quickly because untreated cases carry a risk of sudden vision loss. If you are over 50 with a new persistent headache, scalp tenderness, jaw pain while chewing, or unexplained fatigue and weight loss, a blood test for inflammation markers is a straightforward first step.
Red Flags That Call for Urgent Evaluation
Most back-of-the-head headaches will not land you in an emergency room. But certain features shift a headache from “probably benign” to “needs investigation now.” A review of secondary headache warning signs highlights several red flags: sudden onset of severe pain, a change in the pattern of a longstanding headache, focal neurological symptoms like weakness or vision changes, seizure, systemic signs such as fever or weight loss, and headache triggered or worsened by physical activity like coughing or exertion.22PubMed Central. Secondary headaches – red and green flags and their significance for diagnostics
A practical way to think about it: a headache that builds gradually, feels familiar in character, and responds to rest or over-the-counter treatment is unlikely to be dangerous. A headache that arrives like a clap of thunder, comes with new neurological symptoms, wakes you from sleep at its worst, or is unlike any headache you have ever had before is the kind that warrants same-day medical evaluation, often with brain imaging.23PubMed Central. Neuroimaging and other investigations in patients presenting with headache
Exercise Headache and the Back of the Skull
Some people notice a headache at the back of the head specifically during or just after strenuous exercise. If the pain is bilateral, lasts anywhere from a few minutes to 48 hours, and shows up only with exertion, it may be primary exercise headache. Large epidemiological studies have found that this type is more common in women and often coexists with migraine.24PubMed Central. Primary Exercise Headache The condition is generally benign, but any new headache triggered by exertion should be evaluated at least once to rule out the dangerous causes mentioned earlier, since subarachnoid hemorrhage and arterial dissection can also be triggered by physical effort. Once serious causes are excluded, exercise headache is typically managed with anti-inflammatory medications or, in recurrent cases, a beta-blocker taken before the activity.
Weightlifters are particularly prone, especially during heavy lifts that involve holding the breath and bearing down. Reducing the Valsalva strain, breathing out during the effort phase, and warming up gradually before high-intensity work can reduce the frequency of exercise-related occipital headaches without requiring medication.
