Frontal Headache: Causes of Forehead Pain and What Helps

What a frontal headache means

"Frontal" refers to the front of the head, the area over the frontal bone. A frontal headache is not a diagnosis by itself. It tells you where the pain is, and the location narrows the possible causes. Pain here can come from the muscles of the forehead and scalp, the sinuses behind the forehead and cheeks, the eyes, or nerves that also supply the face. Many headaches that start at the back of the head or neck spread forward to the forehead, too.

Most frontal headaches are primary headaches, meaning the headache is the condition itself (tension-type headache, migraine, cluster headache). A smaller number are secondary headaches, caused by something else such as a sinus infection, an eye problem, a medicine or, rarely, a serious illness.

Common causes of frontal headache

Tension-type headache

The most common cause of forehead pain in adults. It feels like a dull, pressing or tight band across the forehead or around the whole head, usually on both sides. It is mild to moderate, does not throb and does not get worse with walking or climbing stairs. You can usually carry on with your day. Stress, poor sleep, long hours at a screen, clenching the jaw and tight neck and shoulder muscles are typical triggers. See tension headache for more.

Migraine

Migraine often causes throbbing pain at one temple or behind one eye, though it can affect the whole forehead. Clues that point to migraine:

• moderate to severe pain that throbs and worsens with activity
• nausea or vomiting
• sensitivity to light, sound or smells
• an aura in some people: zigzag lines, flashing lights or a blind spot lasting 5 to 60 minutes before the headache
• attacks lasting 4 to 72 hours, often with a family history

Many people who believe they have "sinus headaches" actually have migraine. Migraine can cause a blocked or runny nose and watery eyes during an attack.

Sinus congestion and sinusitis

The frontal sinuses sit just above the eyebrows. When their lining swells during a cold or allergy flare, you can feel pressure across the forehead and cheeks that gets worse when you bend forward. A true sinus infection, acute sinusitis, comes with thick yellow or green discharge, a blocked nose, reduced smell and sometimes fever. Forehead pain without nasal symptoms is rarely from the sinuses.

Eye strain and uncorrected vision

Reading, driving or screen work with an uncorrected vision problem (farsightedness, astigmatism or age-related presbyopia) makes the focusing muscles work hard. The result is an ache across the brow and around the eyes that builds through the day and eases with rest. Squinting and holding things farther away to read are clues. An eye test often fixes it.

Dehydration, hunger and caffeine withdrawal

Not drinking enough, skipping meals and missing your usual caffeine can all trigger a frontal headache. Caffeine withdrawal typically starts 12 to 24 hours after the last dose and can last a few days. Dehydration headaches ease within an hour or two of drinking fluids.

Medication-overuse headache

Taking pain relievers on too many days (simple pain relievers on 15 or more days a month, or triptans, combination painkillers or opioids on 10 or more days a month) can cause a daily or near-daily headache. It is often worse on waking. Reducing the medicines, with your doctor's help, is the treatment. See medication-overuse headache.

Other common triggers

• Colds, flu and COVID-19, which often cause a forehead ache with fever
• Alcohol and hangovers
• Poor sleep or obstructive sleep apnea (morning headaches)
• Cold foods ("brain freeze"), which cause a brief, sharp forehead pain
• Jaw clenching and teeth grinding

Less common but serious causes

Frontal headache by type of pain

Frontal headache between the eyes

Pain centered between the eyes, at the bridge of the nose, is most often from tension headache, sinus congestion (the ethmoid sinuses sit here) or eye strain. Migraine and cluster headache can also focus here. A single painful red eye with blurred vision is a different matter and needs urgent eye care.

How doctors find the cause

A doctor diagnoses most headaches from the story, so it helps to keep a headache diary for a few weeks. Expect questions about:

• where the pain is, what it feels like and how bad it gets
• how quickly it starts and how long it lasts
• other symptoms: nausea, light sensitivity, aura, blocked nose, eye symptoms, fever
• triggers such as stress, sleep, food, alcohol, screens and the menstrual cycle
• how often you take pain relievers and caffeine
• family history of migraine

The exam includes blood pressure, the eyes (including the back of the eye), the sinuses, neck muscles, scalp and temples, and a check of nerves, strength and coordination. Tests are only needed when something does not fit: a CT or MRI scan for warning signs, blood tests (ESR, CRP) for suspected giant cell arteritis, eye pressure measurement for glaucoma, or a lumbar puncture for suspected meningitis or bleeding.

How to relieve a frontal headache

Right now

• Drink water and eat if you have skipped a meal.
• Rest in a quiet, dim room if light or noise bother you.
• Apply a cool cloth to the forehead, or warmth to tight neck and shoulder muscles.
• Take a break from screens and look at distant objects for a few minutes.
• Try an OTC pain reliever such as acetaminophen (paracetamol), ibuprofen, naproxen or aspirin. Follow the label dose. Take it early in a migraine. Do not give aspirin to children or teenagers. Avoid NSAIDs if you have stomach ulcers, kidney disease or take blood thinners.

Treating the cause

• Sinus congestion: saline nasal rinses, steam and a short course of decongestant spray (no more than 3 days). For allergy, a steroid nasal spray.
• Migraine: prescription triptans or newer migraine medicines if OTC treatment is not enough, plus preventive treatment if attacks are frequent.
• Eye strain: an eye test and glasses or updated lenses, the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds), and better screen lighting.
• Tension-type headache: stress management, regular exercise, physical therapy for neck and posture, and sometimes a preventive medicine such as amitriptyline for frequent headaches.
• Medication overuse: cutting back on pain relievers under medical guidance. Headaches often get worse for a week or two before they improve.

Prevention

• Keep regular sleep and meal times.
• Drink fluids through the day and keep caffeine steady and moderate.
• Limit alcohol.
• Take regular breaks from screens and set up your workstation so your neck is not strained.
• Limit pain relievers to 2 or 3 days a week to avoid rebound headaches.

When to worry about a frontal headache

Most forehead headaches are not dangerous. Get help quickly if the headache is sudden and severe, new after age 50, comes with fever and a stiff neck, neurological symptoms (weakness, numbness, speech or vision problems), follows a head injury, or is steadily getting worse. A change in your usual headache pattern is also a reason to see a doctor.

Frequently asked questions

What does a frontal headache mean?

It means headache pain located at the front of the head: the forehead, temples or between the eyes. It describes where the pain is, not the cause. Most frontal headaches come from tension-type headache, migraine, sinus congestion, eye strain, dehydration or caffeine withdrawal.

What are the most common causes of frontal headache in adults?

Tension-type headache is the most common, followed by migraine. Other frequent causes are sinus congestion from colds or allergies, eye strain from screens or uncorrected vision, dehydration, skipped meals, caffeine withdrawal, hangovers, poor sleep and overuse of pain relievers.

How do I know if my forehead headache is from my sinuses?

A sinus headache comes with a blocked or runny nose, thick discolored mucus, reduced smell, and pressure that worsens when you bend forward, often during or after a cold. Forehead pain without nasal symptoms, or with nausea and light sensitivity, is more likely migraine or tension headache.

Can stress cause a frontal headache?

Yes. Stress is the most common trigger for tension-type headaches, which often feel like a tight band or pressure across the forehead. Stress also triggers migraine. Regular sleep, exercise, breaks from work and relaxation techniques reduce how often these headaches happen.

When should I worry about a headache in my forehead?

Seek urgent care for a sudden, explosive headache, a headache with fever and stiff neck, weakness, confusion, vision loss or speech problems, a headache after a head injury, or a new headache after age 50 with scalp tenderness or jaw pain. Steadily worsening headaches also need assessment.

Can dehydration cause a frontal headache?

Yes. Even mild dehydration can cause an ache across the forehead, often with tiredness, dark urine and thirst. Drinking water usually relieves it within an hour or two. If it persists after rehydrating, look for another cause.
