Migraine Postdrome: How Long the Migraine Hangover Lasts

Migraine postdrome is the recovery phase that follows the headache in a migraine attack. The pain has stopped, but you may still feel drained, slow, or unwell, which is why many people call it a migraine hangover. Understanding what is typical makes it easier to plan your recovery and to notice when lingering symptoms need a closer look.

What is migraine postdrome?

Postdrome is the final phase of a migraine attack, beginning once the head pain has resolved. The International Classification of Headache Disorders defines the postdrome as a symptomatic phase lasting up to 48 hours after the pain resolves, with fatigue, elated or depressed mood, and cognitive difficulties among its common symptoms.

A migraine attack can move through up to four phases: prodrome, aura, headache, and postdrome. Not everyone has every phase, and the boundaries are blurry. The American Migraine Foundation notes that there is considerable overlap between phases; brain fog, for example, can appear before, during, and after the headache. Our guide to how long a migraine lasts explains the earlier phases.

Postdrome is common. The American Migraine Foundation estimates that around 80% of people with migraine experience it, and the Cleveland Clinic also reports that more than 80% do.

What does postdrome feel like?

Postdrome often feels like being worn out after an illness: the main event has passed, but your body and concentration have not caught up. Symptoms vary between people and between attacks.

These symptoms are drawn from the Migraine Trust’s guide to the migraine hangover and the Cleveland Clinic. Thinking difficulties can be the most disruptive part of recovery; our article on migraine brain fog covers them in more depth.

The upbeat version surprises some people. Feeling unusually energetic after an attack is a recognized postdrome experience, not a sign that the attack was mild.

How long does postdrome last?

Postdrome usually lasts from a few hours to a day or two. The Migraine Trust says it can last from hours to a day or even multiple days, and that most people find it resolves within 24 hours. The ICHD-3 definition sets the outer limit at 48 hours.

The length of your postdrome may not follow the severity of the attack. The Migraine Trust describes a 2016 study that found no clear link between how severe an attack was and how long the postdrome lasted, and no link with the medication taken during the attack. Individual experiences still vary, which is why your own record is more useful than a general average.

A short headache can therefore cost you more time than it seems. An attack with six hours of pain followed by a day of exhaustion has affected two days, and your records should show both.

Can postdrome last for weeks?

Symptoms that persist for weeks fall outside the usual description of postdrome. They deserve a medical review rather than an assumption that this is simply a long migraine hangover. The Cleveland Clinic advises seeing a healthcare provider if non-headache postdrome symptoms last more than 48 hours.

Several situations can make it feel as if recovery never finishes. These are possibilities for a clinician to assess, not self-diagnoses:

• Attacks close together. If a new attack begins before you have recovered from the last, the warning phase of one can run into the recovery phase of another. Frequent attacks are a reason to see a doctor in their own right.
• Chronic migraine. Headache on 15 or more days a month for more than three months, with migraine features on at least 8 of those days, meets the ICHD-3 criteria for chronic migraine. See our guide to chronic migraine for how to count headache days.
• Medication-overuse headache. The Migraine Trust describes medication-overuse headache as a persistent headache that develops when acute treatments are used more and more often. The ICHD-3 criteria depend on the type of medicine and the number of use days. Do not stop or change prescribed medicines on your own; discuss frequent use with a clinician.
• An attack that has not ended. A debilitating attack continuing for more than 72 hours is classified as status migrainosus. This is different from postdrome because the headache phase itself continues, and it needs prompt medical advice.
• Aura symptoms that do not go away. Aura symptoms persisting for a week or more are rare, and ICHD-3 describes persistent aura without infarction only after brain imaging has ruled out a stroke. Visual or other aura symptoms that last longer than usual need medical assessment.
• Something other than migraine. Ongoing tiredness, low mood, dizziness, or poor concentration have many possible causes. A clinician can consider sleep, mood, other illnesses, and medicines alongside your migraine history.

When should you get medical help?

Get help based on the symptom, not on whether it might be part of a migraine. The NHS migraine page sets out these thresholds:

If you are outside the UK, use your local emergency number and urgent-care services. Postdrome symptoms that are new for you, much stronger than usual, or not improving are also reasons to check in with a clinician.

What can help during postdrome?

There is no proven cure for the migraine hangover, but practical self-care can make recovery easier. The Migraine Trust and the Cleveland Clinic both suggest a similar set of approaches:

• Rest and sleep when you can, without feeling you have to make up for lost time at once.
• Drink fluids and eat regular, manageable meals.
• Try gentle movement, such as stretching, if it feels comfortable.
• Use a heat pad or an ice pack for neck or muscle aches.
• Reduce bright light and loud noise while you remain sensitive.
• Plan a lighter day. If your records show that your postdrome usually lasts a day, you can schedule demanding tasks with that recovery time in mind.

Be patient with yourself. Feeling slow after an attack is part of the migraine, not a lack of effort. Our guide on how to stop a migraine covers what you can do earlier in an attack.

How can you track your postdrome?

Record two moments: when the head pain ended and when you felt like yourself again. The gap between them is your postdrome, and it is often missing from headache records that stop when the pain does.

A useful postdrome entry includes:

• The time the head pain ended
• Recovery symptoms such as tiredness, brain fog, or neck stiffness, with rough times
• How the recovery affected work, study, or home life
• When you felt back to normal, marked as an estimate if you are unsure

Here is a hypothetical example: “Head pain ended 22:00 Tuesday. Wednesday: very tired, slow reading at work, stiff neck until lunch. Felt normal by Wednesday evening (estimated).” Over several attacks, entries like this show whether your recovery is usually hours or days, and whether it is changing.

Keep recovery days distinct from headache days. A day of postdrome fatigue without head pain is not another headache day, but it still affected your life, and that impact is worth sharing with your clinician. Our migraine journal template shows how to keep these entries short.

In Calma, you can log when an attack started and ended, select symptoms such as fatigue, brain fog, or dizziness, and use notes to record recovery timing. Exported PDF or CSV reports can then help you discuss your full attack pattern, recovery included, at your next appointment.

Frequently Asked Questions

These answers cover common questions about the recovery phase.

How long does migraine postdrome last?

Postdrome usually lasts from a few hours to a day or two after head pain ends. The Migraine Trust notes that most people find it resolves within 24 hours, and the ICHD-3 classification describes it as lasting up to 48 hours.

Can migraine postdrome last for weeks?

Weeks of lingering symptoms fall outside the usual description of postdrome. Frequent attacks, a prolonged attack, medication-overuse headache, or an unrelated condition may be involved, so ask a clinician to review symptoms that last that long.

What are the most common postdrome symptoms?

Commonly reported symptoms include tiredness, difficulty concentrating, a stiff neck or body aches, sensitivity to light or sound, dizziness, and mood changes. Some people instead feel unusually energetic or elated.

Is it still a migraine if I feel fine after the headache?

Yes. Not everyone has a noticeable postdrome. Around 80% of people with migraine report one, so feeling well soon after head pain ends does not mean the attack was something else.
