Migraine Symptoms: Warning Signs to Recognize Early

A migraine typically causes throbbing, one-sided head pain along with nausea and sensitivity to light or sound, lasting anywhere from four hours to three days if untreated. But the headache is only one part of the picture — many people also experience warning signs a day or two before the pain starts, and a "hangover" feeling for a day or two after it ends.

Migraine isn't just a headache. It's a neurological condition, and the pain phase is often bracketed by other symptoms that are easy to miss or misattribute to something else.

The Four Stages of a Migraine Attack

Most descriptions of migraine break it into four possible stages: prodrome, aura, headache (or "attack"), and postdrome. Not everyone experiences all four in every attack, and the stages can overlap.

1. Prodrome (Early Warning Signs)

This phase can begin one to two days before the headache itself. Common signs include:

• Mood changes, from irritability to unexpected euphoria

• Food cravings

• Neck stiffness

• Frequent yawning

• Increased thirst and urination

• Constipation

• Fatigue or trouble concentrating

Because these symptoms are subtle and nonspecific, many people don't connect them to an oncoming migraine until they've tracked several attacks.

2. Aura

Roughly a quarter of people with migraine experience aura, usually in the 30 to 60 minutes before the headache begins, though it can also overlap with the pain. Aura symptoms are reversible and typically build gradually over several minutes.

The most common aura symptoms are visual: flashing lights, zigzag lines, blind spots, or blurred vision affecting both eyes. Aura can also involve tingling or numbness in the face or hand, and in some cases, temporary difficulty finding words or speaking clearly.

Migraine with aura is considered a distinct clinical category from migraine without aura, and it carries a modestly increased risk of stroke — one reason a first-time aura, especially in someone with cardiovascular risk factors, is worth discussing with a doctor.

3. Headache (Attack Phase)

This is the stage most people associate with migraine. Typical features include:

• Throbbing or pulsing pain, often on one side of the head

• Pain that worsens with physical activity or even mild movement

• Nausea, sometimes with vomiting

• Sensitivity to light (photophobia), sound (phonophobia), and sometimes smell

• In children, the headache may be less prominent, with nausea, vomiting, or dizziness as the main signs

Untreated, the headache phase commonly lasts between four hours and three days.

4. Postdrome ("Migraine Hangover")

After the headache fades, many people feel drained for hours or up to two days. This postdrome phase can include fatigue, difficulty concentrating, neck stiffness, mood changes, and lingering sensitivity to light. Research suggests a large majority of people with migraine experience some postdrome symptoms, even if the headache itself was brief.

[REVIEWER: add clinical insight here — for example, guidance you give patients on pacing activity during postdrome versus pushing through.]

Less Obvious Migraine Symptoms

Because migraine affects more than just pain pathways, some symptoms don't look like a typical headache at all. Patients frequently report:

• Dizziness or a vague sense of imbalance

• Difficulty concentrating or "brain fog"

• Feeling too hot or too cold

• A sensation of head pressure or heaviness without classic throbbing pain

• Increased heart rate or body distortion sensations

These atypical presentations are one reason migraine often goes undiagnosed, particularly when the headache itself is mild or absent.

When Migraine Symptoms Need Emergency Care

Most migraines, while disruptive, aren't dangerous. But certain symptoms overlap with more serious conditions and need immediate medical attention:

• A headache that reaches full intensity within seconds ("thunderclap" headache)

• Headache with a high fever, stiff neck, confusion, seizures, or double vision

• New numbness, weakness, or slurred speech that doesn't resolve

• A headache pattern that is new after age 50, or that is clearly different from your usual migraines

These can signal conditions like meningitis, stroke, or bleeding in the brain, which require urgent evaluation rather than home management.

Tracking Your Symptoms

Because migraine symptoms vary so much between individuals — and even between attacks in the same person — keeping a simple log of when symptoms start, what they involve, and how long each stage lasts can help a healthcare provider identify patterns, triggers, and the right treatment approach.

FAQ

What is usually the first sign of a migraine? For many people, the first sign is a prodrome symptom appearing one to two days before the headache — often mood changes, neck stiffness, food cravings, or unusual yawning. These signs are subtle and easy to overlook until a pattern becomes familiar.

Can you have a migraine without a headache? Yes. Some people, especially children, experience migraine mainly as nausea, vomiting, or dizziness with little or no head pain. Aura can also occur without a following headache in some cases.

How long do migraine symptoms last? A full attack, including prodrome and postdrome, can span 8 to 72 hours. The headache phase itself typically lasts four hours to three days if untreated.

What's the difference between migraine aura and the headache itself? Aura is a set of reversible sensory or speech symptoms — often visual disturbances — that can precede or accompany the headache, usually lasting under an hour. The headache phase is the throbbing pain stage that follows.

When should I see a doctor about migraine symptoms? See a doctor if headaches are frequent, severe, or disrupt daily life, and seek emergency care for a sudden "worst-ever" headache, headache with fever and stiff neck, or new neurological symptoms like weakness or slurred speech.

Takeaway

Migraine rarely announces itself as just "a bad headache." Recognizing the prodrome signs, understanding what aura looks and feels like, and knowing which symptoms are red flags can help you get ahead of an attack — and know when a headache needs more than rest and quiet.
