Migraine Prodrome Symptoms: The Early Signs That a Migraine Is Coming

By Laurine NicolettiOctober 26, 202611 min

You have been yawning all afternoon, even though you slept fine. You are oddly snappy with your flatmate, your neck feels tight, and all you want is something sweet. Then, a few hours later, the headache arrives and you think: "Of course." Those clues are known as migraine prodrome symptoms.

Those quiet clues are called migraine prodrome symptoms. They are the early signals your body can send in the hours (sometimes the day or two) before the pain starts. This article explains what they look like, why they happen, how they differ from triggers, and how to start noticing your own. It sits within our guide to migraine symptoms, if you want the bigger picture.

In short

The prodrome is the first phase of a migraine attack, and it can bring yawning, food cravings, a stiff neck, mood changes and tiredness before any head pain.
It can start from a few hours to about two days before the headache, and not everyone with migraine notices one.
A prodrome symptom is not a trigger: a sugar craving may be a sign the attack has already begun, not what caused it.
Writing down what you feel and when helps you recognise your own pattern and gives your doctor useful information.

What is the migraine prodrome?

The prodrome is the earliest phase of a migraine attack, before the headache and before any aura. The American Migraine Foundation also calls it the "preheadache" or premonitory phase, and says it can last anywhere from a few hours to several days.

Think of it as the body's weather forecast. The storm has not arrived, but something in the air has shifted. The prodrome is different from aura, which are temporary sensory changes such as flashing lights that usually come right before or with the pain. If you want to untangle the other words doctors use, our migraine glossary explains them simply.

What are the signs that a migraine is coming?

The most common early signs are yawning, food cravings, neck stiffness, mood changes and fatigue. The American Migraine Foundation lists neck pain and stiffness, vision changes, dizziness, foggy thinking, trouble concentrating, moodiness and irritability among the usual suspects, along with excessive yawning and cravings for certain foods.

The NHS describes similar clues: feeling very tired and yawning a lot, craving certain foods or feeling thirsty, mood changes, a stiff neck, or peeing more. The Mayo Clinic adds constipation and fluid retention, and mentions mood shifts that can swing from low to unusually upbeat.

Here is how these signs often show up in daily life:

Yawning that feels constant and out of proportion to how tired you are.
Food cravings, often for sweet or salty things, or a sudden strong thirst.
A stiff or tender neck, without having slept badly or sat hunched over.
Irritability, low mood or restlessness, sometimes a strange burst of energy.
Brain fog, trouble concentrating or finding words.
Sensitivity to light, sound or smells that is slightly higher than usual.

Your own list may include only two or three of these, and it can look different from your friend's. That is normal. If a stiff neck is your main clue, our article on migraine neck pain explains why it can be an early sign and how to tell it apart from a neck problem.

Why does the brain send these signals?

The honest answer is that researchers do not fully know, but they think the hypothalamus and other brain areas are involved early on. The hypothalamus is a small region deep in the brain that helps manage appetite, sleep, thirst and mood.

A review for clinicians by Dara Jamieson in Clinician.com notes that some prodrome symptoms correlate with activation of specific brain areas: the hypothalamus (for example food craving), the trigemino-cervical complex (neck pain) and the visual cortex (light sensitivity). That fits with what many people feel: appetite, sleep and mood all wobble at once.

This does not mean the headache is "in your head" in the dismissive sense. It means the migraine process seems to begin before the pain, which is one reason it helps to read what happens in your brain during a migraine.

How long before the pain does the prodrome start?

It usually starts hours to about two days before the head pain, but the timing varies a lot from person to person. The NHS says early symptoms start hours or up to 2 days before the head pain. The Mayo Clinic says one or two days, while Cleveland Clinic describes the prodrome as beginning up to 24 hours before a headache.

Those numbers are not contradictory. They reflect that the warning window changes between people, and even between your own attacks. Some mornings you may feel "off" for a full day; other times it is a couple of hours. For the full timeline of an attack, see how long a migraine lasts.

Does everyone have a prodrome?

No, but many people do, and a lot of them do not realise it. According to the American Migraine Foundation, about 75% of people with migraine have a prodrome, but often do not recognise it as the start of an attack.

A large survey backs this up. In the CaMEO International study, 66.9% of 14,492 respondents with migraine in six countries (including the UK, US and Canada) reported pre-headache symptoms. Other studies report very different figures, from roughly a third to over 90% of people, depending on how the question is asked. So the real number is uncertain, and "I don't notice anything" is a completely valid experience.

The same CaMEO paper found that people who had both pre-headache and post-headache symptoms also reported more headache days per month. That is an association in a survey, not proof of cause, and it does not mean having a prodrome says anything bad about you.

Prodrome or trigger: how not to mix them up

A trigger is something that may help set off an attack, while a prodrome symptom is a sign that the attack has already started. The two get confused because they happen in the same window of time.

The classic example is chocolate. Many people rank it as their top food trigger, but Jamieson's review in Clinician.com points out that placebo-controlled studies have not shown that chocolate triggers migraine. A craving for it may instead be a prodromal symptom. The American Migraine Foundation explains the same idea: in that case the attack would have happened whether or not you ate the chocolate.

The same can apply to other things:

Neck tension you blame on your desk, when it may be the first sign.
Light sensitivity you blame on bright screens.
A bad mood you blame on a stressful day.
Skipped meals or odd eating that began because your appetite had already changed.

This does not mean triggers are a myth. Sleep, stress, hormones and some foods and drinks are genuinely linked to attacks for many people, and our guides to identifying your triggers and to migraine and food look at the evidence. The point is to be gently curious before you cut something out of your life for good.

How can you spot and note your own signs?

The simplest method is to write down how you felt in the 24 to 48 hours before each attack, then look for patterns after a few weeks. You do not need a perfect diary. A few words in the same place each time is enough.

Try this after each migraine:

Note when the pain started, as best you remember.
Look back 48 hours and write anything that felt unusual: yawning, cravings, mood, neck, energy, concentration, thirst.
Mark what you ate, slept and did, separately from the symptoms, so that you can compare later.
Notice the repeats. After four or five attacks, signs that keep returning are likely part of your prodrome.

It also helps to note the days when you felt "off" but no migraine followed. That is how you learn how reliable each sign is for you. Our guide on what to write in a migraine diary covers the useful details.

Parents may also find this helpful for younger people, who can struggle to describe early feelings. Our article on migraine in children and teens explains how attacks can look different at those ages.

What can you do when you notice the signs?

There is no proven routine that works for everyone, so the best first step is to treat the signs as information and to talk to your doctor about a plan. You can note the time, check how you feel over the next few hours, and give yourself a little space if your day allows it.

If you take medication for attacks, when and how to take it is a question for your doctor or pharmacist, not something to guess. Our overview of migraine medication explains the main options in general terms. Some people also get relief from simple non-drug approaches, which we cover in how to relieve a migraine without medication.

Spotting the prodrome does not mean you can always stop the attack. Sometimes the main benefit is emotional: you can plan, tell someone, and feel less caught off guard.

When should you talk to a doctor?

Book an appointment if your migraines are getting worse, lasting longer than usual, happening more than once a week, or hard to control. The NHS gives these as reasons to see a GP. Bring your notes about early signs; they help a clinician see your pattern.

Sudden, severe or unusual symptoms are different and need urgent care. Our guide on when to go to the ER for a migraine explains the warning signs, and when to see a doctor shows how to prepare for the visit.

The takeaway: your body may be talking early

The prodrome is the quiet first phase of a migraine, and learning your own signals can make attacks feel a little less like a surprise. Yawning, cravings, a stiff neck and irritability are common, but your list is personal.

Keep short notes, stay curious about what is a sign and what is a trigger, and share your findings with your doctor. You are not imagining it, and you do not need to get it perfect.

Frequently asked questions

What are the most common migraine prodrome symptoms?

The most common ones include yawning, food cravings, neck stiffness, tiredness, mood changes and trouble concentrating. The American Migraine Foundation lists these among typical prodrome signs, and the NHS also mentions thirst and needing to pee more.

Is the prodrome the same as an aura?

No. The prodrome is a broader early phase that can last hours to a day or two, while aura is a short sensory disturbance such as flashing lights or tingling, which the NHS says should not last longer than an hour. You can have a prodrome with or without aura.

Can a food craving cause a migraine?

Probably not. The American Migraine Foundation explains that a craving may be part of the prodrome, meaning the attack had already started before you ate. If you want to understand your food patterns, talk to your doctor and track them over time.

Can you have a prodrome without a headache following?

Possibly, though research on this is limited. Some people have "off" days without a migraine, which is why noting signs and outcomes together helps you learn how reliable each sign is for you.

Do I need a doctor if I notice early warning signs?

Early signs alone are not a reason to worry. See a doctor if your attacks are frequent, getting worse or hard to control, and bring your notes with you.
