The reason you want to lie completely still during a migraine is not weakness or preference — it is a defining feature of the condition. Aggravation by, or avoidance of, routine physical activity is one of the four headache characteristics in the diagnostic criteria for migraine. Walking upstairs making your head pound is not a detail to mention in passing; it is one of the things that makes a headache a migraine rather than something else.
That also makes it one of the highest-value things to record, because it is a criterion your clinician is actively assessing.
It Is Literally in the Diagnostic Criteria
Under the criteria for migraine without aura, the headache must have at least two of four characteristics:
- Unilateral location
- Pulsating quality
- Moderate or severe pain intensity
- Aggravation by, or causing avoidance of, routine physical activity — the classification gives walking or climbing stairs as the examples
Note the phrasing carefully. It counts if the activity makes the pain worse, and it counts if the pain makes you avoid the activity. People who have learned to stay still often answer "no" to "does movement make it worse?" because they stopped moving years ago. That is a yes.
Why This Is Such a Useful Discriminator
This criterion is one of the cleaner separators between migraine and tension-type headache. Tension-type headache is typically not aggravated by routine physical activity — many people find walking makes no difference or even helps a little. Migraine characteristically gets worse.
Our comparison of tension headache and migraine covers the full set of distinguishing features, and the headache types comparison chart puts them side by side.
Two practical notes:
- The examples matter. "Routine physical activity" means walking or stairs, not exercise. If you have to think about whether it applies, use the stairs test.
- Avoidance counts as much as aggravation. Lying in a dark room and staying still is the behaviour the criterion is designed to capture.
What It Is Not
A few distinctions worth keeping separate:
- Headache brought on by exertion — starting during or after exercise, rather than an existing headache worsening with movement — is a different pattern. A new exertional headache needs medical assessment, particularly the first time.
- Headache worse specifically on coughing, straining or bending forward is a distinct and more concerning pattern than general movement sensitivity. See the warning below.
- Movement making you nauseated or dizzy rather than worsening the pain points more toward a vestibular pattern.
That second one is the important one. "Worse when I walk about" and "worse when I cough or bend over" sound similar and are clinically very different.
When Movement-Related Headache Needs Assessment
Seek urgent assessment for a headache that is consistently worse on coughing, sneezing, straining or bending forward, or that is worse when lying flat and better when upright (or the reverse) — these positional patterns need investigation. Seek emergency care for a headache that comes on suddenly during exertion and peaks within seconds, or for exertional headache with vomiting, neck stiffness, vision changes, weakness or confusion. A first-ever headache triggered by exercise, sex, or straining warrants prompt medical review.

What to Track
This is a criterion your clinician will ask about directly, so bring the answer:
| Field | Why |
|---|---|
| Did routine activity worsen it? | Criterion 4, stated in the classification's own terms |
| Did you avoid activity because of it? | Counts equally — and is what most people actually do |
| Worse on coughing/straining/bending? | A different, more concerning pattern — record separately |
| One-sided? | Criterion 1 |
| Pulsating or throbbing? | Criterion 2 |
| Moderate or severe? | Criterion 3 |
Recording all four turns "I get bad headaches" into a description that maps directly onto how the diagnosis is made. That is a materially better appointment.
The migraine symptom checker walks through these features in the order a clinician would, and the migraine vs tension headache checker focuses specifically on the comparison where this criterion does most of its work. Tracking the four features across attacks in Migraine Trail produces a report that answers the diagnostic questions before they are asked.
