Pain between the eyebrows usually traces back to one of a handful of causes: tension in the small muscles of the forehead, sinus inflammation, eyestrain, migraine variants that target the mid-face, or irritation of the supraorbital nerve that runs right through that area. The spot feels specific, but the anatomy beneath it is a busy intersection of sinuses, muscles, and nerve branches, which is exactly why so many different problems can produce pain in the same place.
The Muscle You Probably Don’t Know About
There is a small muscle called the corrugator supercilii that sits right between and above your eyebrows. Its job is to pull your brows together when you squint, frown, or concentrate. If you spend hours staring at a screen, reading in poor light, or clenching your face during stressful tasks, this muscle can go into a sustained contraction that generates a dull, pressing ache in exactly that spot. This is the classic tension-type headache localized to the glabellar region, the patch of skin between your brows.
A small clinical study tested what happens when the corrugator muscle is surgically cut in patients with chronic headaches originating from the forehead. In nine of ten patients, average pain scores dropped from about 8 out of 10 down to less than 1, and all nine stopped needing daily pain medication for their frontal headaches.1SpringerLink (J Neural Transm). Corrugator supercilii transection for headache emanating from the frontal region: a clinical evaluation of ten patients That is not a treatment most people need, but it illustrates how directly this one small muscle can drive the pain you feel in that location. For most people, the practical takeaway is simpler: if you catch yourself furrowing your brow while working, consciously relax it. Frequent screen breaks, better lighting, and even gentle massage across the brow line can reduce the tension that builds up there over the course of a day.
Sinus Pain and Its Common Imitators
The frontal sinuses sit directly behind the bone between your eyebrows, so when they become inflamed or infected, they can produce a deep, pressure-like pain in precisely this spot. Acute sinusitis typically comes with other symptoms: congestion, thick nasal discharge, a reduced sense of smell, and sometimes a low fever. If you have those alongside the forehead pressure, sinusitis is a reasonable explanation.
Here is the catch, though: many people who assume they have sinus headaches actually don’t. A study of over 100 patients who came to a nasal clinic complaining of facial pain found that every single one who had both a normal nasal endoscopy and a clean CT scan turned out to have a neurological diagnosis rather than sinus disease. None of them improved with sinus treatments. The most common actual diagnoses were migraine, rebound headache from overusing pain medication, and chronic daily headache.2PubMed. Endoscopy-negative, computed tomography-negative facial pain in a nasal clinic A follow-up study of a similar population found that the most frequent neurological diagnosis in these “sinus pain” patients was migraine, accounting for about 37% of cases, and that roughly 58% improved once they started the right medical therapy.3PubMed. Neurologic diagnosis and treatment in patients with computed tomography and nasal endoscopy negative facial pain
So if you keep getting pain between your eyebrows but your nose feels fine, you don’t have discolored discharge, and decongestants do nothing for you, it is worth considering that your “sinus headache” may be something else entirely.
Eyestrain and Uncorrected Vision
Prolonged close-up work, whether reading, coding, or scrolling on a phone, forces the muscles inside and around your eyes to sustain a focused effort for hours. That effort often results in what clinicians call asthenopia, or simply eyestrain, and one of its most common symptoms is a headache centered around the forehead and temples. A survey of over 400 medical students who used computers regularly found that about 47% reported migraines or headaches as an early symptom of their eyestrain, alongside tired eyes, burning, and temporary blurred vision.4Taylor & Francis Online (Arch Environ Occup Health). Accommodative asthenopia among Romanian computer-using medical students-A neglected occupational disease
Uncorrected or under-corrected vision problems make this worse. Research comparing headache patients with non-headache patients in an optometry clinic found that even mild refractive errors, particularly mild farsightedness and certain types of astigmatism, were significantly more common in the headache group. The headaches these patients reported tended to cluster around the temples and the temporo-frontal area, right at and between the brows.5The British and Irish Orthoptic Journal. Exploring Correlations between Headaches and Refractive Errors in an Optometry Clinic Sample You don’t need a dramatic prescription to get headaches from your eyes. Sometimes a slight farsightedness that barely affects your daily vision is enough to make the muscles around your brows work overtime and ache by the end of the day. If you haven’t had a full eye exam in a while, especially if your between-the-brows pain worsens with reading or screen time, that is a low-hanging fruit worth checking.
When It Is Actually Migraine
Migraine has a reputation for being an intense, throbbing, one-sided headache with nausea and light sensitivity. That description is accurate for many episodes, but migraine can also show up as a steady ache or pressure across the forehead, centered between or above the eyebrows, without the dramatic pounding that people associate with the word. This is part of the reason so many migraine sufferers go undiagnosed or wrongly assume they have sinus trouble.
In a study of nearly a thousand consecutive patients seen at a rhinology clinic, about 42% had facial or head pain. Among those, about 12% turned out to have migraine. Of the migraine patients, roughly 63% felt the pain in the forehead, eye, or cheek area.6Wiley Online Library / Blackwell Science / PubMed Central. Facial migraine in a rhinological setting These people had gone to a nose-and-sinus specialist because the pain felt like it was in their sinuses, not in their head in the classic migraine sense. The distinguishing clues are often in the accompanying features: does the pain get worse with bright light or loud noise? Does it come with nausea? Does physical activity make it worse? Does it tend to cycle, lasting hours to days and then resolving? If you answer yes to several of those, the pain between your eyebrows may be a migraine variant rather than anything structural.
Supraorbital Neuralgia
A nerve called the supraorbital nerve exits the skull through a small notch right at the inner edge of your eyebrow. When this nerve becomes irritated or compressed, it produces a sharp, localized pain in or just above the brow that can radiate toward the forehead. This condition, supraorbital neuralgia, is uncommon but distinctive. It accounts for a small fraction of facial pain cases, roughly 4% in one clinical report, and is defined by three features: pain in the territory the supraorbital nerve supplies, tenderness when you press on the notch where the nerve exits, and temporary but complete relief when the nerve is numbed with a local anesthetic.7PubMed Central. Trigeminal neuralgia involving supraorbital and infraorbital nerves
The pain is usually one-sided, persistent, and may come with slight numbness in the forehead skin above the affected eye. Clinical observation has shown that patients tend to have clear tenderness at the nerve’s exit point and that repeated nerve blocks reliably reduce the pain, which helps clinicians confirm the diagnosis.8PubMed. Supraorbital neuralgia. On the clinical manifestations and a possible therapeutic approach If your pain is sharply localized to one brow and you can pinpoint a tender spot right at the inner edge of the eyebrow, this is worth bringing up with a doctor. The good news is that once identified, it often responds well to nerve blocks or anti-inflammatory treatment.
Trochleitis and Pain Near the Inner Eye
Another underappreciated cause of pain in the between-the-brows area is trochleitis, an inflammation of the trochlea, a tiny pulley-like structure in the inner upper corner of each eye socket through which one of the eye muscles passes. When inflamed, it produces a deep, aching pain very close to the bridge of the nose and inner eyebrow that can be mistaken for sinusitis or migraine. In a clinical trial that screened over 1,100 patients presenting with eye pain and migraine symptoms, 33 were found to have trochleitis confirmed by orbital MRI.9PubMed Central. The effect of nonsteroidal anti-inflammatory drugs on eye pain and migraine headache caused by trochleitis That is a small fraction, but for those individuals, recognizing the correct diagnosis meant targeted treatment with anti-inflammatory drugs rather than ongoing, unsuccessful migraine or sinus therapy.
Trochleitis tends to produce pain that is worse when you look up or move your eyes in certain directions, and you may be able to reproduce the discomfort by pressing gently on the inner upper corner of the eye socket. If you notice those patterns, it is a clue worth mentioning to your doctor, because the condition does not show up on standard sinus imaging and is easy to miss if nobody thinks to look for it.
Glaucoma as a Hidden Cause
This one is less common but more dangerous. Acute angle-closure glaucoma happens when the drainage system inside the eye suddenly becomes blocked, causing a rapid spike in eye pressure. The symptoms can include eye redness, worsening vision, headache, and nausea.10PubMed Central. Acute Closed-Angle Glaucoma-an Ophthalmological Emergency That headache often settles around the forehead and brow on the affected side and can easily be mistaken for a migraine or sinus problem, especially in its subacute form.
A case series described three patients who were initially diagnosed with headache syndromes before being found to have subacute angle-closure glaucoma. In each case, the eye looked normal on casual inspection and there were no obvious visual symptoms. Only a comprehensive ophthalmologic exam revealed the real problem, and a straightforward laser procedure cured the headaches completely.11PubMed. Subacute angle-closure glaucoma as a cause of headache in the presence of a white eye The key warning signs are pain on one side that comes with any visual change, even subtle halos around lights, or that builds up in the evening or in dim environments when the pupil naturally dilates. This is a medical emergency in its acute form and should be evaluated promptly even in its milder presentations, because untreated glaucoma can permanently damage vision.
Lifestyle and Environmental Triggers
Sometimes the explanation is less about pathology and more about what your body has been going through recently. Skipping meals is a well-documented headache trigger. The mechanisms are not fully settled, but low blood sugar and caffeine withdrawal have been singled out as likely contributors to fasting-related headaches.12PubMed. Fasting headache: a review of the literature and new hypotheses If you tend to get that between-the-brows ache on days you skip breakfast or go longer than usual without eating, the timing is probably not coincidental. Caffeine withdrawal in particular can produce a frontal headache that settles right across the brow line, and it can start within 12 to 24 hours of your last cup of coffee.
Altitude changes are another trigger that specifically targets the area between the eyebrows. The frontal sinuses sit right behind that bone, and when cabin pressure drops during a flight or you drive up a mountain, the air trapped in your sinuses can expand or contract faster than it can equalize through the sinus openings. A case report described a man who developed acute frontal headache radiating specifically to the inter-eyebrow region after a commercial flight, diagnosed as frontal sinus barotrauma from the sinus opening being blocked during altitude changes.13Europe PMC / JBR-BTR. Frontal Sinus Barotrauma If you notice this pattern during flights, using a decongestant nasal spray before descent can help keep the sinus openings clear.
Other common triggers that tend to concentrate pain in the forehead area include dehydration, alcohol (especially red wine), sleep deprivation, and sudden changes in weather or barometric pressure. These are not specific to the between-the-brows spot, but because the frontal sinuses and the corrugator muscle are right there, environmental headache triggers often feel most intense in that particular location.
When to Take It Seriously
Most pain between the eyebrows is benign and resolves with rest, hydration, or simple over-the-counter pain relief. But there are specific patterns that warrant a prompt medical evaluation. A clinical review of headache red flags catalogued the warning signs that should prompt further workup. Among them:
- Sudden onset: A headache that reaches peak intensity within seconds, sometimes called a thunderclap headache, needs emergency evaluation to rule out bleeding in the brain.
- Neurologic symptoms: Weakness, numbness, confusion, trouble speaking, or vision loss alongside the headache.
- New onset after age 65: First-time headaches in older adults can signal conditions like giant cell arteritis, which involves inflammation of blood vessels and can threaten vision if untreated.
- Progressive worsening: A headache that gets steadily worse over days or weeks rather than cycling normally.
- Fever and systemic symptoms: Pain accompanied by high fever, unexplained weight loss, or night sweats.
- Pain triggered by coughing or straining: Headaches brought on specifically by bearing down, sneezing, or exercise can indicate pressure-related problems.
- Eye redness or visual changes: As discussed in the glaucoma section, this combination needs urgent eye evaluation.
These red flags were compiled in what researchers call the SNNOOP10 list, a systematic checklist of secondary headache warning signs.14PubMed Central. Red and orange flags for secondary headaches in clinical practice: SNNOOP10 list If none of these apply to you and the pain is mild to moderate, episodic, and tracks with obvious triggers like screen time, stress, or skipped meals, you can reasonably start with lifestyle adjustments and over-the-counter treatments before seeking a specialist evaluation.
Medication Overuse and the Rebound Trap
One pattern that keeps people stuck with chronic between-the-brows pain deserves its own mention. If you reach for ibuprofen, acetaminophen, or a triptan more than two or three days a week for several weeks running, you can develop medication-overuse headache, sometimes called rebound headache. The pain medications that initially helped start to perpetuate the very headache they were meant to treat, creating a cycle where the headache returns as each dose wears off, prompting another dose. In the study of facial-pain patients referred for neurological evaluation, rebound headache accounted for about 17% of diagnoses, making it one of the most common findings.3PubMed. Neurologic diagnosis and treatment in patients with computed tomography and nasal endoscopy negative facial pain The fix is counterintuitive: you have to stop the overused medication, endure a few rough days while the rebound cycle breaks, and then switch to a preventive strategy rather than relying on frequent acute treatment. This is best done with guidance from a doctor, especially if the headaches are severe.
Nasal Contact Points and Structural Quirks
Inside the nose, the septum (the wall dividing the two nasal passages) is rarely perfectly straight. When a sharp bony spur on the septum presses against the opposite nasal wall, the contact point can generate referred pain that radiates to the forehead, brow, or even the ear on the same side. A case report documented a 19-year-old with a five-year history of ear pain and ringing that turned out to be caused by a large nasal septal spur pressing against the lateral nasal wall. Applying local anesthetic inside the nose relieved the symptoms, and surgically removing the spur resolved them.15Europe PMC. Nasal Septal Spur Associated with Rhinogenic Contact Point Otalgia and Tinnitus While this particular patient’s primary complaint was ear pain rather than forehead pain, the mechanism of mucosal contact-point pain has been studied across multiple sites in the nasal cavity and can refer pain to the forehead and inter-brow area as well. These contact points are not always visible without nasal endoscopy, which is one reason an ENT evaluation can be helpful if conventional treatments for your between-the-brows headache aren’t working.
Structural causes like these tend to produce pain that is constant or near-constant rather than episodic, and that stays on one side. If your pain is always on the same side, doesn’t throb or pulse, and doesn’t have obvious migraine features, a structural explanation becomes more plausible.
Giant Cell Arteritis in Older Adults
For people over 50 who develop new-onset pain in the forehead or temple area, one condition that doctors should screen for is giant cell arteritis, an inflammatory disease affecting medium and large blood vessels. The temporal arteries, which run along the temples, are most commonly involved, but the condition can affect blood vessels elsewhere in the head and face. One clinical review noted that the aorta and its branches are involved in about 25% of patients with giant cell arteritis.16Continuum. The Eye and Headache The headache from giant cell arteritis tends to be new, persistent, and sometimes accompanied by scalp tenderness, jaw pain when chewing, or visual disturbances. Left untreated, it can cause permanent vision loss, so a new persistent headache in someone over 50, especially with those accompanying symptoms, warrants a blood test for inflammatory markers and sometimes a temporal artery biopsy. This is one of the clearest examples of a between-the-brows headache that cannot safely be managed with over-the-counter painkillers alone.
