A migraine is far more than a bad headache. It’s a neurological event that unfolds in distinct phases, producing symptoms that can start a full day or two before the head pain begins and linger after it ends. The headache itself typically lasts 4 to 72 hours untreated, with throbbing or pulsing pain that’s moderate to severe. But many people are surprised to learn that head pain is only one piece of a much larger picture.
Early Warning Signs: The Prodrome
One or two days before the headache hits, subtle changes can signal that a migraine is building. These early symptoms are easy to overlook or chalk up to a bad night’s sleep, but recognizing them gives you a window to act. Common prodrome signs include:
- Unusual food cravings
- Mood shifts, from feeling unusually happy to irritable or depressed
- Neck stiffness
- Increased thirst and more frequent urination
- Constipation
- Frequent yawning, even when well-rested
Not everyone experiences a prodrome, and the specific signs vary from person to person. Over time, though, many people learn to recognize their own pattern. That early recognition can be valuable because some treatments work best when taken before the pain phase starts.
Aura Symptoms
About a quarter to a third of people with migraines experience aura, a set of temporary sensory disturbances that typically develop within minutes and last up to an hour. Aura usually appears shortly before the headache, though it can overlap with the pain itself.
Visual disturbances are the most common type. You might see zigzag lines that slowly drift across your field of vision, shimmering spots or stars, flashes of light, or a blind spot (sometimes outlined by a simple shape like a circle). These tend to start near the center of your vision and spread outward.
Aura can also affect other senses. A tingling feeling may start in one hand and creep up the arm, eventually reaching the face, lips, or tongue, sometimes turning into numbness. Some people have trouble finding words or speaking clearly. These symptoms can be alarming the first time they happen because they mimic signs of a stroke, but migraine aura builds gradually over several minutes rather than striking all at once.
The Headache Phase
The headache is what most people think of when they hear “migraine,” and it’s distinct from a tension headache in several ways. The pain is typically throbbing or pulsing rather than a steady squeeze. It often affects one side of the head, though it can shift sides between attacks or, in some cases, affect both sides at once. The intensity is moderate to severe, enough to interfere with your ability to work, concentrate, or carry on a normal conversation.
Physical activity makes it worse. Something as simple as walking up a flight of stairs or bending over to pick something up can intensify the pain. This is one of the reasons people with migraines instinctively retreat to a dark, quiet room and stay still.
Alongside the pain, the headache phase brings a cluster of other symptoms:
- Sensitivity to light (photophobia) so intense that even normal indoor lighting feels harsh
- Sensitivity to sound (phonophobia) where ordinary conversation or background noise becomes unbearable
- Sensitivity to smell where perfume, cooking odors, or cleaning products can trigger or worsen nausea
- Nausea and vomiting, which can be severe enough to prevent you from keeping oral medication down
If a migraine goes past the 72-hour mark without relief, it’s classified as status migrainosus, a prolonged attack that typically requires medical intervention.
The “Migraine Hangover”
Once the headache fades, many people assume the migraine is over. It isn’t. A postdrome phase, often called a migraine hangover, can follow and last anywhere from several hours to a day or more. During this phase you may feel drained, foggy, and not quite yourself.
Common postdrome symptoms include fatigue that rest doesn’t seem to fix, difficulty concentrating or making decisions, a stiff or achy neck, lingering nausea, continued sensitivity to light and sound, and dizziness. Mood swings are also typical. Some people feel inexplicably euphoric after an attack, while others feel depressed. The cognitive fog can be particularly frustrating because you look fine to everyone around you even though your brain feels like it’s running at half speed.
Migraines Without Head Pain
It’s possible to have a migraine with no headache at all. These are sometimes called silent migraines or acephalgic migraines. You experience the prodrome and aura symptoms (visual disturbances, tingling, numbness, difficulty speaking, dizziness, even ringing in the ears) but the pain phase never arrives. The visual and sensory symptoms typically come on within minutes and can last up to an hour.
Silent migraines are more common in people who had migraines with aura earlier in life. They can be confusing to experience because without the headache as a reference point, the visual disturbances or sudden trouble speaking may seem to come out of nowhere. If you develop these symptoms for the first time, it’s worth getting evaluated to rule out other neurological causes.
Vestibular Migraine: When Dizziness Is the Main Symptom
Vestibular migraine is a variant where dizziness and balance problems take center stage, sometimes with a headache and sometimes without one. The hallmark symptom is vertigo, a spinning sensation that can last anywhere from a few minutes to several hours, and in some cases, days. You may also feel unsteady on your feet, have trouble with motion sensitivity (feeling sick in a car or while scrolling on a phone), and experience the typical nausea, light sensitivity, and sound sensitivity of a conventional migraine.
Because the headache component can be mild or absent, vestibular migraines are frequently misdiagnosed as inner ear problems or anxiety. If you have recurring episodes of unexplained dizziness, especially if you have a personal or family history of migraines, this variant is worth discussing with your doctor.
Symptoms That Are Not a Typical Migraine
Most migraines, while miserable, follow a recognizable pattern. Certain symptoms break that pattern and point to something more serious. Pay attention to these red flags:
- Sudden, explosive onset. A headache that reaches maximum intensity within seconds (sometimes called a “thunderclap headache”) can signal a vascular emergency like a brain aneurysm. Migraines build over minutes to hours, not seconds.
- New neurological symptoms. Weakness in an arm or leg, new or unusual numbness, or vision changes that don’t fit your typical aura pattern warrant immediate evaluation.
- Steady worsening over weeks. Migraines tend to be episodic, coming and going. A headache that progressively gets more severe or more frequent over time is a red flag.
- Fever, night sweats, or unexplained weight loss alongside headaches can indicate an underlying systemic condition.
- Headache that changes with position. Pain that significantly worsens when you stand up or lie down, or that’s triggered by coughing or straining, may point to a pressure issue in or around the brain.
- New headache during or after pregnancy. Hormonal shifts during pregnancy are common migraine triggers, but a brand-new headache pattern in this period needs evaluation for conditions like blood vessel abnormalities.
Any of these scenarios calls for prompt medical attention rather than assuming it’s just another migraine.
