A headache at the back of your head is most often caused by tension, poor posture, or strain in the muscles and joints of your upper neck. Less commonly, it can signal nerve irritation, a cervical spine problem, or something that needs urgent medical attention. The location alone doesn’t point to one diagnosis, but the type of pain, how it starts, and what comes with it can help narrow things down.
Tension-Type Headaches
The most common cause of pain at the back of the head is a tension-type headache. These produce a feeling of tightness or pressure across the forehead, sides, and back of the head, often accompanied by tenderness in the scalp, neck, and shoulder muscles. The pain is usually dull and steady rather than sharp or throbbing, and it can last anywhere from 30 minutes to several days.
Stress is the most frequently reported trigger. Despite older theories blaming muscle contractions in the face and neck, current thinking points to an increased sensitivity to pain in people who get these headaches regularly. That heightened sensitivity may explain why the muscles feel tender even though they aren’t actively cramping. Other common triggers include poor sleep, dehydration, skipped meals, and eye strain from prolonged screen time.
Posture-Related Pain
If you spend hours looking at a phone or computer, forward head posture may be the culprit. Tilting your head forward places extra stress on the muscles and soft tissues at the back of your neck, particularly a group of deep muscles at the base of your skull called the suboccipital muscles. These muscles shorten and tighten in response to the abnormal position, and over time they can develop trigger points: hyperirritable spots in the muscle that send referred pain upward across the back and sides of the head, sometimes reaching the temples.
Forward head posture also limits head and neck movement and impairs the neck’s ability to sense its own position accurately, which can contribute to dizziness alongside the headache. Correcting posture, adjusting your workstation so your screen sits at eye level, and stretching the neck throughout the day are the most direct fixes.
Cervicogenic Headaches
A cervicogenic headache starts in the neck but is felt in the head. The pain originates from irritation of structures in the upper cervical spine, specifically the joints, discs, or muscles supplied by the top three spinal nerves. These nerves feed into the same pain-processing center that handles signals from the head and face, so your brain interprets the neck problem as head pain, typically at the base of the skull and sometimes behind one eye.
About 70% of cervicogenic headaches trace back to a joint between the second and third cervical vertebrae. The pain is usually one-sided, worsens with certain neck movements, and may be accompanied by reduced range of motion. Neck trauma, whiplash injuries, arthritis in the upper spine, and chronic muscle spasms can all set the stage. Treatment typically involves physical therapy targeting neck mobility and strength, and in persistent cases, nerve block injections or other interventions aimed at the specific joint causing the problem.
Occipital Neuralgia
Occipital neuralgia is a distinct condition involving the nerves that run from the upper neck to the back of the scalp. The hallmark is paroxysmal shooting or stabbing pain in the posterior scalp, recurring in bursts that last from a few seconds to minutes. The pain is severe and sharp, sometimes described as electric. Between episodes, a dull ache may linger.
This differs from a tension headache in both quality and intensity. Tension headaches feel like pressure; occipital neuralgia feels like jolts. The pain typically follows a specific path from the base of the skull upward along one or both sides of the back of the head. The scalp in that area may be extremely tender to touch. Causes include compression or irritation of the occipital nerves from tight muscles, injury, or inflammation. Diagnosis often involves pressing on the nerve at the base of the skull to see if it reproduces your pain.
Exercise Headaches
Strenuous physical activity can trigger headaches during or shortly after a workout, particularly during running, rowing, weightlifting, or swimming. Primary exercise headaches usually affect both sides of the head, including the back, and last between five minutes and 48 hours. Hot, humid weather and high altitude increase the risk.
These headaches are generally harmless, but a headache that appears for the first time during exercise should be evaluated. Secondary exercise headaches, caused by an underlying problem like a blood vessel abnormality, tend to last longer (at least a day, sometimes several) and may come with other symptoms like vomiting, vision changes, or neck stiffness.
When the Pain Signals Something Serious
Most headaches at the back of the head are not dangerous, but certain patterns warrant immediate medical attention. A thunderclap headache, pain that reaches maximum intensity within seconds to a minute, is considered a medical emergency. In people who present with this type of headache, subarachnoid hemorrhage (bleeding around the brain) is found in 11 to 25% of cases, and other types of intracranial bleeding in another 5 to 10%.
A sudden, severe headache paired with any of the following is a red flag:
- Neck stiffness and fever, which may indicate meningitis
- Confusion, seizures, or loss of consciousness, which can accompany bleeding in the brain
- Neck pain with a drooping eyelid, a possible sign of an arterial tear in the neck
- Vision changes, nausea, or the worst headache of your life, which call for emergency imaging
Severely elevated blood pressure, at readings of 180/120 or higher, can also cause intense headaches. This is called a hypertensive crisis, and it requires emergency treatment to prevent organ damage.
Managing Recurring Posterior Headaches
For tension and posture-related headaches, over-the-counter pain relievers like acetaminophen, ibuprofen, or naproxen are effective when taken at the first sign of symptoms. One important rule: limit their use to two days or fewer per week. Using them more often can cause rebound headaches, where the medication itself starts triggering more frequent pain.
Non-medication strategies make a meaningful difference over time. Resting in a cool, dark, quiet room with a cold compress on the neck or base of the skull can cut short an active headache. For prevention, the basics matter more than any single treatment: regular physical activity, consistent sleep, adequate hydration, and stress management techniques like biofeedback, which trains you to control muscle tension and other stress responses. Keeping a headache diary that tracks when pain occurs, what you ate, how you slept, and what you were doing helps identify patterns that are easy to miss otherwise.
For cervicogenic headaches and occipital neuralgia, targeted physical therapy or manual therapy focused on the upper neck is the first-line approach. If those don’t provide relief, nerve blocks or other procedures directed at the specific source of irritation are the next step.
