Tension Headache or Migraine? How to Tell Them Apart

Most headaches are not dangerous, but they are not all the same either. The two you are most likely to meet are tension-type headaches, the most common kind, and migraine, which MedlinePlus reports affects about 12% of Americans. They respond to different treatments, so knowing which one you tend to get is worth the effort.

This page compares the two side by side, explains how painkillers can backfire, and sets out the rare warning signs that mean calling 911. It can help you understand your pattern and decide what to do next, but it cannot diagnose you. Only a clinician can do that.

What is the difference between a tension headache and a migraine?

A tension headache is usually a dull, pressing ache on both sides of the head that you can work through, while a migraine is usually a throbbing, often one-sided pain that is moderate to severe and comes with nausea or sensitivity to light and sound. Some migraines also begin with an aura, a set of temporary nervous system symptoms such as flashing lights or zigzag lines.

Both are primary headaches, meaning the headache is the condition itself rather than a symptom of something else. That is reassuring: MedlinePlus notes that tension headaches are not associated with brain diseases. Secondary headaches, caused by another problem such as an infection, an injury, or bleeding, are much less common, and the red flags later on this page are how you spot them.

Because sleep, posture, stress, and activity all feed into both types, headaches are closely tied to the rest of your everyday physical health, and small changes in those areas often matter as much as medicine.

How do tension headaches and migraines compare?

The table sets out the typical features of each. Few people tick every box, so look for the overall pattern rather than any single feature.

Feature	Tension-type headache	Migraine
Location	Both sides, often a band across the forehead, temples, or back of the head and neck	Often one side, commonly behind an eye or at the back of the head; can switch sides
Quality of pain	Dull, pressing, or tightening; not throbbing	Throbbing, pounding, or pulsing
Severity	Mild to moderate; you can usually carry on	Moderate to severe; often hard to work or function
How it starts	Gradually, often after long hours at a desk or a stressful day	A dull ache that builds over minutes to hours, sometimes after early warning signs
How long it lasts	30 minutes to 7 days	Usually 4 to 72 hours
Nausea or vomiting	Usually absent	Common
Light and sound sensitivity	Usually absent, or mild	Common, often both
Aura	No	In some people: zigzag lines, flashing lights, blind spots, or tingling before the pain
Effect of moving around	Usually not made worse by routine activity	Often worse with movement, so many people want to lie still
Afterward	Usually nothing lingers	Often a hangover of fatigue, fogginess, and neck pain for up to a day

If your headaches mostly match the middle column, a tension-type headache is the likelier fit. If they throb, keep you from working, and make light or noise hard to bear, migraine is more likely, even if you have never had an aura. It is also possible to have both types at different times.

What does a tension headache feel like?

A tension headache usually feels like a dull, steady pressure, often described as a tight band or a vise around the head. According to MedlinePlus, the pain is felt all over rather than in one spot or on one side, and it tends to be worst at the scalp, temples, or back of the neck, sometimes spreading into the shoulders.

It does not usually throb, and nausea and vomiting are usually absent. You may notice that the muscles of your neck, shoulders, or scalp feel tight or tender to the touch. MedlinePlus notes that the pain can last anywhere from 30 minutes to 7 days, and episodes can be occasional or, for some people, almost daily.

Tension headaches are linked to tightening of the neck and scalp muscles, which can be a response to stress, anxiety, depression, or injury. Holding your head in one position for a long time, such as at a computer, is a classic setup.

What does a migraine feel like?

A migraine usually feels like a throbbing, pounding, or pulsing pain, often on one side of the head, that builds from a dull ache over minutes to hours. MedlinePlus describes the pain as moderate to severe, commonly felt behind one eye or at the back of the head and neck, and says an attack typically lasts 4 to 72 hours.

What sets migraine apart is what comes with the pain. Nausea, vomiting, and sensitivity to light and sound are common, and many people want to lie still in a dark, quiet room. Migraine usually first appears between ages 10 and 45, often runs in families, and women are about three times more likely to have it than men.

What is a migraine aura?

An aura is a group of temporary nervous system symptoms that can come before the headache, or occasionally without one. The most common are visual: flashing lights, zigzag lines, blind or colored spots, blurring, or tunnel vision. Some people have tingling or numbness instead.

According to MedlinePlus, an aura usually starts 10 to 15 minutes before the headache, and a headache does not always follow. Many people with migraine never have an aura at all, so its absence does not rule migraine out.

What are the phases of a migraine?

MedlinePlus describes four possible phases, though not every attack includes all of them:

• Prodrome: subtle early warning signs, sometimes up to 24 hours before the pain
• Aura: visual disturbances or tingling, in some people
• Headache: the throbbing pain, often with nausea and sensitivity to light and sound
• Postdrome: exhaustion, fogginess, or confusion that can last up to a day, sometimes called a migraine hangover

What triggers tension headaches and migraines?

Many triggers are shared, which is one reason the two are easy to confuse. According to MedlinePlus, stress, sleep problems, alcohol, skipped meals, and too much caffeine or caffeine withdrawal can set off either type.

Common tension headache triggers

• Stress, anxiety, and fatigue
• Long stretches at a screen with your head held still, a common side effect of sitting in one posture all day
• Jaw clenching or teeth grinding
• Eye strain
• Sleeping in a cold room or with your neck at an awkward angle
• Colds, flu, or sinus infections
• Alcohol and heavy smoking

Common migraine triggers

• Hormonal changes, such as around a menstrual period or with birth control pills
• Too much or too little sleep
• Bright lights, loud noise, and strong smells
• Skipped meals
• Weather changes
• Alcohol, especially red wine, and some foods, such as aged cheese, chocolate, MSG, and cured meats
• Intense exercise or other physical stress

Triggers vary widely from person to person. A headache diary, noting what you ate, how you slept, your stress level, and, if you menstruate, where you are in your cycle, is the most practical way to find your own. Sleep deserves special attention, because sleep and mental health are closely linked, and a run of poor nights can feed both headaches and low mood.

Stress sits on both trigger lists. When worry is constant and headaches are only one of its effects, it helps to know the signs of anxiety that needs professional help.

Can taking painkillers too often cause headaches?

Yes. Using headache medicine too often can cause medication-overuse headache, also called rebound headache, in which the medicine itself keeps the headaches coming. MedlinePlus warns that taking pain relievers more than 3 days a week may lead to rebound headaches, whether you have tension headaches or migraine.

The pattern tends to creep up. Headaches become more frequent, you reach for relief sooner and more often, and each dose seems to help for less time. Over-the-counter pain relievers, combination products that contain caffeine, and some prescription migraine medicines can all be involved.

There are other reasons to keep count. MedlinePlus notes that too much acetaminophen can harm the liver, and nonsteroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen and naproxen) can irritate the stomach or damage the kidneys. If you find you need pain relief more than 3 days a week, talk to your doctor, who can help you break the cycle safely and consider preventive treatment.

How are tension headaches and migraines treated?

Both usually respond best to treatment taken early, but the options differ. Tension headaches often ease with over-the-counter pain relievers and self-care, while migraine may need specific prescription medicine, and frequent attacks of either can be prevented rather than only treated.

Tension headaches

MedlinePlus lists over-the-counter pain relievers such as acetaminophen, ibuprofen, naproxen, or aspirin, along with massage, ice or heat on the neck, relaxation training, and biofeedback (a technique that teaches you to control muscle tension using feedback from sensors). Good posture, neck and shoulder stretches, enough sleep, and staying warm may help prevent them. For frequent tension headaches, doctors sometimes prescribe a tricyclic antidepressant as a preventive.

Migraine

For mild attacks, over-the-counter pain relievers may be enough. Triptans are the most commonly prescribed migraine medicines, and MedlinePlus notes that migraine medicines work best when taken early in an attack. Resting in a dark, quiet room, a cold compress on the forehead, and drinking fluids can also help.

If you have frequent attacks, daily preventive treatment may make sense. Options include certain blood pressure medicines, antidepressants, and anti-seizure medicines, as well as newer medicines that block a protein called CGRP. Some migraine medicines narrow blood vessels, so tell your doctor if you have heart disease risk factors or are pregnant.

Stress management is part of prevention for both types. Relaxation techniques and a regular practice such as mindfulness for beginners will not replace medicine for everyone, but they are low risk and may reduce how often stress tips you into a headache.

Which headache symptoms mean you should call 911?

Call 911 for a headache that comes on suddenly and explosively, or one that comes with signs of a stroke or a serious infection. These are rare compared with everyday tension headaches and migraines, but they are emergencies where minutes matter.

What is a thunderclap headache?

A thunderclap headache is a severe headache that starts suddenly and reaches full strength within about a minute. MedlinePlus describes it as the typical headache of a subarachnoid hemorrhage (bleeding in the space around the brain), which people often call the worst headache ever and unlike any they have had before. It may start after a popping or snapping feeling in the head and can come with a stiff neck, vomiting, sensitivity to light, or confusion. Call 911 even if the pain begins to ease.

What are the signs of a stroke?

The CDC lists these sudden stroke signs:

• Numbness or weakness in the face, arm, or leg, especially on one side of the body
• Confusion, trouble speaking, or difficulty understanding speech
• Trouble seeing
• Trouble walking, dizziness, loss of balance, or lack of coordination
• A severe headache with no known cause

The CDC's B.E. F.A.S.T. stroke check is easy to remember: Balance loss, Eye or vision changes, Face drooping on one side, Arm drifting down when both are raised, Speech slurred or strange, Time to call 911. Note when symptoms started, because treatment options depend on timing.

Migraine aura can cause vision changes, tingling, or trouble speaking that look like a stroke. Aura symptoms usually build gradually over several minutes and then fade, while stroke symptoms usually start suddenly, but you cannot safely tell them apart at home. If it is your first aura, it feels different from your usual pattern, or weakness is involved, call 911. MedlinePlus also notes that migraine is a risk factor for stroke, especially in people who smoke and in women who have migraine with aura.

Warning sign	Why it matters	What to do
Sudden, explosive headache that peaks within about a minute	Can signal bleeding around the brain	Call 911
Headache with face drooping, one-sided weakness or numbness, slurred speech, or sudden trouble seeing	Can signal a stroke	Call 911 and note the time symptoms began
Headache with fever and a stiff neck	Can signal meningitis, an infection of the membranes around the brain and spinal cord	Call 911 or go to the emergency room
Headache with confusion, fainting, or a seizure	Can signal a serious brain problem	Call 911
Headache after a blow to the head	Can signal bleeding or a brain injury	Get emergency care right away
Headache with repeated vomiting	Can signal a serious underlying cause	Go to the emergency room
Headache with eye or ear pain	Can signal an infection or eye problem that needs prompt treatment	Seek care right away

When should you see a doctor about headaches?

See your doctor if your headaches are frequent, getting worse, or changing, even when none of the emergency signs apply. A clinician can confirm which type you have, check for other causes, and offer treatment that fits your pattern.

Make an appointment if:

• Your usual headache pattern or pain changes, or a new type of headache starts, especially after age 50
• You need pain relievers for headaches more than 3 days a week
• Treatments that used to work stop working, or cause side effects
• Headaches get worse when you lie down, or wake you from sleep
• You are pregnant or could be pregnant
• You have migraines and take birth control pills
• Headaches regularly keep you from work, school, or daily life

Bring a headache diary if you can, recording when each headache started, where it hurt, what it felt like, what came with it, and what you took. It gives your doctor far more to work with than memory alone.
