A headache in the back of your head is most often caused by tension in the muscles of your neck and scalp. It can also come from nerve irritation, neck joint problems, or in rare cases, a spike in blood pressure. The location alone doesn’t point to one diagnosis, but the type of pain, how it starts, and what makes it worse can help narrow things down.
Tension-Type Headaches
This is the most common culprit. Tension headaches produce mild to moderate pain that feels like constant pressure, often described as a band tightening around the head. The pain is usually on both sides and extends to the back of the head and neck. It doesn’t throb. Walking, climbing stairs, and other routine physical activity won’t make it worse, which is one way to tell it apart from a migraine.
Episodes can last anywhere from 30 minutes to seven days. If they happen fewer than once a month, they’re considered infrequent. If they show up on 15 or more days per month for at least three months, they’re classified as chronic tension headaches, and the pain can feel nearly constant.
Stress, poor sleep, skipped meals, and dehydration are common triggers. But for many people, the biggest driver is posture.
How Posture Causes Back-of-Head Pain
Forward head posture, the position your head drifts into when you hunch over a phone or laptop, is one of the most overlooked causes of headaches at the base of the skull. When your head sits forward of your shoulders, a group of small muscles at the top of your neck (just below the skull) have to work overtime to keep your head upright. Those muscles tighten and refer pain upward across the back of your head.
This pattern often coexists with what’s called upper crossed syndrome: the muscles in the front of your chest and the back of your neck become tight and shortened, while the muscles in your upper back and the front of your neck become weak and stretched. The result is a self-reinforcing cycle. Your shoulders round forward, your chin juts out, your neck muscles lock up, and tension headaches follow. If you spend most of your day sitting at a desk or looking at a screen, this is worth investigating before anything else.
Cervicogenic Headaches
A cervicogenic headache starts in your neck and radiates upward to the back of your head, sometimes reaching your forehead or the area behind your eye. Unlike tension headaches, the pain is typically locked to one side. Turning your head or holding it in certain positions makes the pain noticeably worse, and pressing on specific neck muscles can reproduce the headache.
The source is a problem in the upper part of your cervical spine: a stiff joint, a disc issue, or tight soft tissue. The nerves in the upper neck share pathways with nerves that supply sensation to the head, so your brain interprets the neck problem as head pain. Imaging sometimes shows changes in the upper cervical spine, but those same changes appear in plenty of people with no headaches at all, so imaging alone doesn’t confirm the diagnosis. The key diagnostic clue is that the headache is consistently triggered by neck movement or sustained neck posture, and your range of motion is reduced.
Occipital Neuralgia
If the pain feels like an electric shock, a sharp stab, or a sudden burning sensation that shoots from the base of your skull upward, occipital neuralgia is a possibility. This condition involves inflammation of the occipital nerves, which run from the top of your spinal cord up through the scalp. It’s rare, but distinctive.
The pain typically begins in the neck and spreads upward. You may also feel stinging or burning on your scalp, or pain behind one eye. The most common cause is a pinched nerve or muscle tightness in the neck. A previous head or neck injury can also set it off. Between flare-ups, the area may feel tender or sensitive to touch.
For many people, massaging the neck and stretching tight muscles helps reduce the frequency of flare-ups. When the pain is severe or persistent, a procedure called an occipital nerve block (an injection near the irritated nerve) can provide relief. When it works, pain typically improves within 20 to 30 minutes, and the effect can last anywhere from several hours to several months, though results vary from person to person.
High Blood Pressure
Moderately elevated blood pressure doesn’t usually cause headaches. But a hypertensive crisis, where blood pressure spikes to 180/120 mm Hg or higher, can cause a severe headache, often felt at the back of the head. This is a medical emergency, especially when accompanied by chest pain, vision changes, or confusion. Most people with a headache at the back of their head are not having a hypertensive crisis, but if you have known high blood pressure and your headache is unusually intense, checking your blood pressure is a reasonable first step.
Exercises That Help
For tension headaches, cervicogenic headaches, and posture-related pain, targeted exercises can reduce both the frequency and severity of episodes. Clinical studies show the best results come from combining stretching with strengthening. A few that are well-supported:
- Chin tucks: Sit or stand with your back straight. Pull your chin straight back (as if making a double chin) without tilting your head up or down. Hold for 10 seconds and repeat. This strengthens the deep muscles at the front of your neck that get weak with forward head posture.
- Neck flexion and extension stretch: Slowly bring your chin toward your chest and hold for 30 seconds to stretch the back of your neck. Then tilt your head back so you’re looking at the ceiling and hold for 30 seconds to stretch the front. Keep the movements slow and gentle.
- Craniocervical flexion exercise: Lie on your back and perform a small nodding motion (not a full chin tuck), holding for 10 seconds. As this gets easier, progress to raising your arms on either side during the hold. Eventually, try the same motion while sitting against a wall without support.
- Shoulder blade squeezes: Squeeze your shoulder blades together and hold. This targets the weak upper back muscles that contribute to rounded shoulders and forward head posture.
Consistency matters more than intensity. A few minutes daily tends to be more effective than occasional long sessions.
When the Pain Is Something More Serious
Most headaches at the back of the head are not dangerous. But certain features signal something that needs urgent evaluation. Clinicians use a set of red flags to identify headaches that could indicate a stroke, a bleed, an infection, or another serious condition:
- Thunderclap onset: Pain that reaches maximum intensity within seconds or minutes, especially if it’s the worst headache you’ve ever had.
- Neurological symptoms: Confusion, double vision, trouble speaking, weakness on one side, seizures, or a change in alertness or personality.
- Fever, chills, or stiff neck: These can indicate meningitis or another infection.
- New headaches after age 50: A first-time severe headache in someone over 50 warrants investigation.
- Progressive pattern: Headaches that are steadily increasing in frequency, severity, or changing in character over weeks.
- Triggered by coughing, straining, or exertion: Headaches that come on with physical effort or bearing down can sometimes indicate a structural problem.
- Positional changes: Pain that gets dramatically worse or better depending on whether you’re lying down or standing up.
Vertebral artery dissection, a tear in one of the arteries running through the neck to the brain, is one uncommon but serious cause of sudden, severe headache at the back of the head. It typically involves one-sided neck pain alongside the headache and can follow a neck injury or sudden neck movement. This is a medical emergency that requires immediate care.
If your headache at the back of your head is mild to moderate, comes and goes, and responds to rest or stretching, it’s very likely muscular or postural. If it’s new, sudden, severe, or accompanied by any of the red flags above, that’s a different situation entirely.
