What Doctors Want You to Understand

Migraine and tension-type headache are not two sizes of the same headache. They are two different conditions.² One is a nervous-system disorder that affects your whole body during an attack. The other is the common "everyday" headache almost everyone has felt.

Here is where it gets confusing. At the mild end, the two can look almost identical. Headache specialists say the hardest call in their field is telling a mild migraine apart from a tension headache.² And many people who get frequent headaches have both at once.²

Two patterns pull in opposite directions. "Tension headache" is the label people reach for by default, for stress headaches, "sinus" headaches, and screen headaches. Migraine, meanwhile, is often missed. It is far more than a bad headache. Worldwide it is the third leading cause of years lost to disability, behind only stroke and a newborn brain condition.¹ So the everyday label gets over-used, and the serious one gets under-recognized.

No blood test or scan names the headache for you.⁵ A doctor makes the call from the pattern: how the pain behaves, what comes with it, how long it lasts, and how often it strikes. That is why your own description of an attack is the most useful thing in the room.

How to Tell the Difference

Most of the time, a handful of features separate the two. No single one settles it, but together they form a pattern.

A simple memory aid clinicians use for migraine is POUND: Pulsing pain, duration Of one day (4 to 72 hours), Unilateral (one-sided), Nausea, and Disabling.⁵ Having four or more of these five features makes migraine the most likely answer.⁵

Some migraine attacks come with an aura. This is a set of nervous-system warning signs that build over several minutes, before or during the headache.² The most common aura is visual: flickering lights, zigzag lines, or a blind spot that drifts across your vision.² Others feel pins and needles, or briefly struggle to find words.² Aura is a strong migraine signal, and a tension headache never causes it.²

One caution about this table: it describes typical attacks, not a rule. Real headaches overlap, and mild migraine is the classic impostor.² Use these features to have a sharper conversation, not to diagnose yourself.

WHAT YOUR DOCTOR IS LOOKING FOR

Not the label you arrived with, but the pattern underneath it. Specifically:

• What travels with the pain. Nausea and light or sound sensitivity are the features that most reliably separate migraine from a tension headache.²

• How many days a month. Frequency changes both the diagnosis and the plan. Headache on 15 or more days a month, for more than three months, is a different situation than the occasional one.²

• Whether it is actually both. Frequent headaches are often a mix, and the mix is easy to miss if only the worst attacks get described.²

• What you have been taking, and how often. Reaching for pain relievers many days a week can quietly turn either headache into a daily one.³

• Anything that does not fit. The features that point away from an ordinary headache are the ones a doctor screens for first.⁵ ⁶

Why the Difference Changes What You Do

The label matters because the two headaches are treated differently.

For a tension headache, the usual first step is an over-the-counter pain reliever. That means paracetamol (also called acetaminophen), aspirin, or an anti-inflammatory such as ibuprofen.³ Most bouts settle without anything stronger.

Migraine has its own toolkit. For an attack, guidelines point to migraine-specific medicines called triptans, often taken with an anti-inflammatory.³ When attacks come often or knock you flat, a doctor may add a preventive medicine. That is one you take regularly to make attacks less frequent, not to stop one that has already started.³ This is a real fork in the road. There is now a newer group of migraine-specific preventive medicines that top headache experts rank among the first to try.⁴

One trap catches both headaches, and it is the most important practical point on this page. Taking acute pain medicines too often can make headaches more frequent, not less. This is called medication-overuse headache.³ The thresholds are lower than most people expect. Triptans, opioids, or combination painkillers taken on 10 or more days a month can drive it. So can everyday pain relievers like paracetamol, aspirin, or ibuprofen taken on 15 or more days a month.³ If you are treating headaches more days than not, that pattern itself is worth raising.

We go deeper on this in our guide to medication-overuse headache.

WHAT CHANGES THE DECISION

Two people with the same diagnosis can be steered toward different plans. These are the factors that move it:

• How often it happens. Occasional headaches are treated as they come. Frequent ones shift the focus toward prevention.³

• How much it disrupts your life. A headache that sends you to bed is weighed differently than one you can work through.⁵

• What you are already taking. A history of frequent painkiller use changes the plan, because easing off the overuse can itself be the treatment.³

• Pregnancy, or the chance of it. Some preventive medicines are not suitable, so this is central to the choice.³

• Your own preference and how you handle side effects. Guidelines ask clinicians to decide this with you, not for you.³

When a Headache Is a Warning Sign

Almost all migraines and tension headaches are not dangerous. But a small number of headaches signal something that needs urgent care. These are worth knowing by heart.

Get emergency help for a headache that:

• hits like a thunderclap — the worst headache of your life, peaking in under a minute⁵ ⁶

• follows a blow to the head⁶

• comes with a fever and a stiff neck⁶

• brings confusion, weakness, numbness, slurred speech, or new vision loss that is not your usual aura⁵ ⁶

• is a brand-new kind of headache that starts after about age 50⁵

Check in with a doctor, less urgently, if your usual pattern changes. That means headaches getting steadily worse, waking you from sleep, or brought on by coughing, straining, or exercise.⁵ These are not reasons to panic. They are reasons to get looked at rather than wait.

Our guide on when a headache is an emergency walks through these signs in detail.

What to Ask Your Doctor

These questions get you further than "what should I take."

1. Based on my pattern, does this look like migraine, tension headache, or both? Naming it is the first real step, and "both" is a common, legitimate answer.

2. How many headache days a month would change your recommendation? Frequency is the number that shifts the plan from treating attacks to preventing them.³

3. Could the medicines I already use be making this worse? Medication-overuse headache is common and easy to miss.³

4. If this is migraine, is it frequent enough to consider preventive treatment? This is worth raising directly, because the options have grown.⁴

5. Which of my symptoms would count as a warning sign I should not ignore? Knowing your own red flags takes the guesswork out of a frightening moment.⁵

QUESTIONS WORTH ASKING

Keep these for the moments a specific decision is on the table.

• If you are starting a headache diary: how many weeks of tracking do you want before we decide?

• Before starting any daily preventive medicine: what should I expect, and how long before we know if it is working?

• If you are pregnant or planning to be: which of my current options need to change?

• If simple pain relievers are not helping: does that point more toward migraine, or toward how often I am taking them?
