A migraine feels like a throbbing or pounding pain, usually on one side of your head, that lasts anywhere from 4 to 72 hours untreated. But the pain is only part of it. Most people also experience intense sensitivity to light and sound, nausea, and a mental fog that can linger for days. A migraine is a full-body neurological event, not just a bad headache.
The Pain Itself
The hallmark sensation is a pulsing, throbbing beat in your head, often synced with your heartbeat. Some people describe it as pounding; others feel a deep, dull ache. Intensity ranges from moderate to severe, and it tends to worsen with any physical activity, even something as minor as walking up stairs or bending over to pick something up.
Pain typically starts on one side of the head, though it can shift to the other side or spread to both. It often settles around the eye, temple, or forehead, but it can radiate into the sinuses, jaw, and neck. This is one reason migraines are frequently mistaken for sinus headaches or tension headaches, especially when the pain wraps around the face.
How It Differs From a Regular Headache
A tension headache usually feels like a band of pressure around your head. It’s uncomfortable, but you can typically push through your day. A migraine is qualitatively different. The pulsating quality is distinct, and it gets worse when you move. Routine activities like turning on a light, opening a window, or having a conversation can feel genuinely unbearable. Most people with a migraine need to stop what they’re doing and lie down in a dark, quiet room.
Doctors diagnose migraine based on a specific pattern: at least five attacks lasting 4 to 72 hours, with pulsating pain that is moderate to severe, one-sided, and worsened by routine activity. During the attack, you also need to have nausea, vomiting, or sensitivity to both light and sound. In children and teenagers, attacks can be shorter, sometimes lasting just two hours.
Sensory Overload
One of the most disorienting parts of a migraine is how your senses turn against you. Light becomes painful (even the glow of a phone screen), normal conversation volume feels too loud, and everyday smells can become intolerable. The scent of fabric softener on your pillowcase, a coworker’s perfume, or food cooking in another room can trigger waves of nausea.
Smell sensitivity affects somewhere between 25% and 80% of people with migraine, depending on the study, and it’s linked to more severe, longer-lasting attacks. Even more striking is a phenomenon called allodynia, where touch that’s normally painless becomes painful. People describe it as “even my hair hurts.” Brushing your hair, the weight of clothing on your skin, or resting your head on a pillow can cause real pain during an attack.
Nausea and Stomach Symptoms
Nausea is so common during migraines that it’s part of the diagnostic criteria. For many people, it’s the symptom that’s most disabling, sometimes more than the head pain itself. Vomiting is also common. These symptoms aren’t just a side effect of pain. The nervous systems that control your brain and your digestive tract interact directly during a migraine, and your stomach can slow down dramatically. One small study found that nearly 80% of participants with migraine met the criteria for delayed stomach emptying during an attack, which helps explain why food feels repulsive and oral medications often don’t absorb properly.
What Aura Looks and Feels Like
About 20% to 30% of people with migraine experience aura, a set of sensory disturbances that usually appear before the headache begins. Aura builds gradually over at least five minutes and can last up to an hour.
Visual aura is the most common type. You might see zigzag lines, shimmering or flashing lights, sparkles, or geometric patterns that start in the center of your vision and spread outward. Some people develop temporary blind spots. It can feel alarming the first time it happens, particularly because it often affects both eyes.
Aura isn’t always visual. Some people get numbness or tingling that starts in one hand and creeps up the arm to the face, lips, and tongue. Others have trouble speaking, slurring words or struggling to find the right ones. Dizziness and ringing in the ears are also possible. These symptoms resolve on their own, but they can be frightening, especially because they mimic stroke symptoms.
Migraine Without the Headache
Some people experience all the aura symptoms (visual disturbances, numbness, speech difficulty, dizziness) without ever developing head pain. This is called a silent migraine. The sensory symptoms come on within minutes and can last up to an hour. You might see flashing lights and feel tingling in your arm, then have it all resolve without any headache following. Silent migraines can still include prodrome symptoms like fatigue, irritability, and nausea, so they’re not necessarily mild. They’re just painless.
The Warning Signs Before an Attack
Many people notice subtle changes hours or even a day before the pain starts. This prodrome phase can include unusual fatigue, neck stiffness, irritability, difficulty concentrating, and food cravings. Some people yawn repeatedly or urinate more frequently than normal. Insomnia, constipation, or diarrhea can also show up. These symptoms are easy to dismiss individually, but over time, many people learn to recognize them as a reliable signal that a migraine is coming.
The “Migraine Hangover”
When the headache finally fades, you’re not necessarily back to normal. The postdrome phase, often called a migraine hangover, can last up to 48 hours. You feel drained, like you’ve been physically ill. Your body aches, especially your neck. Concentrating on a task or making a decision feels disproportionately hard. Light sensitivity may still linger. Many people describe this phase as feeling like they’re in a fog: present but not quite functional.
This phase catches a lot of people off guard because the pain is gone, so they expect to feel fine. In reality, the full timeline of a migraine, from the first warning signs through the hangover, can stretch across several days.
The Cognitive Effects
Brain fog is a consistent feature throughout a migraine, not just during postdrome. During an attack, you may lose your train of thought mid-sentence, forget words you use every day, or find it impossible to follow a conversation. Reaction time slows. Reading becomes difficult. Even after the pain subsides, these cognitive effects can persist, making it hard to return to work or handle routine responsibilities right away.
This mental cloudiness is part of what makes migraine so disabling beyond the pain. It’s not just that your head hurts. It’s that your entire ability to think, perceive, and function is temporarily compromised.
