A migraine is far more than a bad headache. It typically produces throbbing pain on one side of the head lasting 4 to 72 hours, accompanied by nausea, sensitivity to light and sound, and sometimes visual disturbances. But many people don’t realize that a migraine attack actually unfolds in distinct phases, each with its own warning signs. Recognizing those signs early can help you respond faster and manage the pain more effectively.
Early Warning Signs Before the Pain Starts
Hours or even days before a migraine headache begins, your body often sends signals that an attack is coming. This early phase is called the prodrome, and learning to spot it gives you a head start on treatment.
Common prodrome signs include:
- Fatigue and difficulty concentrating
- Neck stiffness or pain
- Increased sensitivity to light, sound, or smell
- Mood changes, such as feeling unusually irritable or low
- Frequent yawning
- Food cravings, especially for sweets like chocolate
- Nausea, dizziness, or increased thirst
- Urinating more often than usual
These symptoms are easy to dismiss individually. A craving for chocolate or an extra yawn doesn’t seem meaningful on its own. But when several of these signs cluster together, they can reliably predict that a headache is on its way. Many people who track their migraines learn to recognize their own personal prodrome pattern over time.
Aura: Visual and Sensory Disturbances
About 30 percent of people with migraines experience aura, a set of sensory disturbances that usually appear 5 to 60 minutes before the headache phase. Aura is one of the most distinctive signs of a migraine, and it can be alarming the first time it happens.
Visual aura is the most common type. You might see flashing lights, zigzag lines, shimmering spots, or a spreading blind spot in your field of vision. These disturbances typically start small and expand outward over several minutes. Some people describe them as looking like the shimmer of heat rising off pavement.
Sensory aura can also occur, producing tingling or numbness that often starts in one hand and slowly travels up the arm, sometimes reaching the face or tongue. Less commonly, aura affects speech, making it temporarily difficult to find words or speak clearly. Some people experience ringing in the ears or dizziness. These symptoms build gradually, which helps distinguish them from the sudden onset of something more serious like a stroke.
Signs During the Headache Phase
The headache itself is typically the most debilitating phase. Pain is usually concentrated on one side of the head, though it can affect both sides. The quality of the pain is characteristically throbbing or pulsing, and it ranges from moderate to severe. One hallmark of migraine pain is that routine physical activity makes it worse. Walking up stairs, bending over, or even just moving around the house can intensify the throbbing.
Alongside the pain, several other signs distinguish a migraine from a regular headache:
- Nausea and vomiting
- Sensitivity to light (you feel the need to retreat to a dark room)
- Sensitivity to sound (normal conversation or background noise feels overwhelming)
- Sensitivity to smell and touch (strong odors or even light pressure on your skin can feel unbearable)
Without treatment, a migraine attack lasts anywhere from 4 to 72 hours. Many people find they can’t work, drive, or carry on with normal activities during this phase. The combination of pain, nausea, and sensory overload forces most people into a quiet, dark space until it passes.
The “Migraine Hangover” Afterward
Once the headache fades, the attack isn’t always over. Many people experience a postdrome phase that feels like a hangover. You may feel drained, achy, and foggy-headed. Concentrating on tasks or making decisions can feel unusually difficult. Some people describe a sense that the room is still slightly spinning, or lingering sensitivity to light and sound that takes time to fully clear.
Mood can swing in surprising directions during this phase. Some people feel euphoric, almost giddy that the pain has passed. Others feel flat or depressed. Neck stiffness and general body aches are also common. This recovery period can last hours to a full day, and resting in a calm environment tends to help it resolve faster.
How Migraines Look Different in Children
Children get migraines too, but their symptoms often don’t match the classic adult pattern. In kids, the headache is more likely to affect both sides of the head rather than just one, often across the forehead or temples. Attacks can also be much shorter, lasting as little as two hours compared to the adult minimum of four. Because of these differences, pediatric migraines are easy to overlook or mistake for tension headaches. Nausea and vomiting tend to be more prominent in children, sometimes overshadowing the headache itself.
Migraine Without Much Headache
Not every migraine comes with intense head pain. Vestibular migraine, for example, centers on vertigo and dizziness rather than a throbbing headache. Episodes can feel like the room is spinning, or like your sense of balance has suddenly shifted. These vertigo episodes vary widely in length: roughly a third of people with vestibular migraine have episodes lasting minutes, another third have attacks lasting hours, and another third experience symptoms that stretch over several days. Nausea, sensitivity to motion, and temporary changes in hearing can accompany the dizziness.
Because the headache may be mild or absent entirely, vestibular migraine is frequently misdiagnosed as an inner ear problem. If you experience recurring episodes of unexplained vertigo, especially if you have a history of migraine or a family history of migraine, it’s worth raising the possibility with your doctor.
Episodic vs. Chronic Migraine
Most people with migraines have episodic attacks, meaning they come and go with headache-free stretches in between. Chronic migraine is diagnosed when headaches occur on 15 or more days per month for more than three months, with at least 8 of those days having migraine features. The shift from episodic to chronic migraine usually happens gradually, and recognizing that your attacks are becoming more frequent is important because treatment strategies differ for each.
Headache Signs That Need Urgent Attention
Most migraines, while painful, are not dangerous. But certain headache features can signal something more serious. A sudden, explosive headache that reaches maximum intensity within seconds, sometimes called a thunderclap headache, can point to a vascular emergency and needs immediate evaluation. A headache accompanied by new neurological symptoms like weakness on one side of the body, sudden numbness, or vision changes that don’t follow the typical gradual pattern of aura also warrants urgent medical attention.
Other warning signs include a new type of headache starting after age 50, headaches that are clearly getting worse over weeks or months in a progressive pattern, headaches that change intensity when you shift positions (standing versus lying down), and headaches accompanied by fever, night sweats, or unexplained weight loss. These features don’t necessarily mean something dangerous is happening, but they fall outside the expected pattern of primary migraine and should be evaluated to rule out other causes.
