Migraine: Symptoms, Causes, Triggers, and Treatment

Migraine is a neurological condition that causes recurrent attacks of headache along with a specific set of accompanying features — it is not just a severe version of an ordinary headache. Our migraine vs. regular headache comparison covers how to tell them apart in more direct detail.

Quick Answer

Migraine is a neurological disorder, not simply a bad headache. A typical attack causes throbbing pain, often on one side of the head, with nausea and sensitivity to light and sound, and can last anywhere from several hours to a few days. Triggers such as stress, poor sleep, skipped meals, and hormonal changes may bring on attacks, but migraine itself has a strong neurological and genetic basis. Most migraine attacks are not dangerous, but a sudden, unusually severe headache, or one with new neurological symptoms, needs urgent medical evaluation rather than being assumed to be a typical migraine.

What Is Migraine?

Migraine is a neurological disorder, and MedlinePlus describes it as a recurring type of headache causing moderate to severe pain that is throbbing or pulsing. It involves changes in brain activity that affect pain pathways and, in some people, produce temporary neurological symptoms known as aura. Migraine is a distinct medical condition with its own diagnostic pattern — it is not simply the most severe point on a spectrum that starts with an ordinary tension headache.

Migraine Symptoms

During the headache phase, the NHS and MedlinePlus describe throbbing or pulsing pain, often on one side of the head, though it can occur on both sides or switch sides. Common accompanying features include:

• Nausea, sometimes with vomiting
• Sensitivity to light (photophobia) and sound (phonophobia), and in some people sensitivity to smells
• Pain that worsens with routine physical activity, such as walking up stairs
• Fatigue and difficulty concentrating
• Neck discomfort or stiffness, which some people notice before or during an attack

Not everyone experiences every feature, and the exact combination varies from person to person and sometimes from attack to attack in the same person.

Migraine Attack Stages

A migraine attack can progress through up to four phases, though not everyone experiences all of them, and the pattern can vary between attacks:

• Prodrome — subtle warning signs, such as mood changes, fatigue, neck stiffness, or food cravings, that can appear hours to a day before the headache starts.
• Aura — temporary neurological symptoms that occur in some people, typically shortly before or alongside the headache.
• Headache phase — the throbbing pain and accompanying symptoms described above, typically lasting from several hours up to a few days.
• Postdrome — sometimes called a "migraine hangover," a period of fatigue, difficulty concentrating, or feeling generally unwell after the headache itself has eased.

Migraine With Aura

Aura refers to temporary, fully reversible neurological symptoms that typically develop gradually over at least five minutes and last between five and sixty minutes, usually shortly before or alongside the headache. The most common form is visual aura — flashing lights, zigzag lines, or blind spots — sometimes followed by sensory symptoms such as tingling or numbness, or brief speech or language difficulty. When more than one type occurs, they usually happen one after another rather than all at once.

Because aura can resemble the neurological symptoms of a stroke or other serious conditions, a first episode of aura, or aura that is unusually prolonged, doesn't resolve, or doesn't fit a person's established pattern, needs prompt medical evaluation rather than being assumed to be a typical migraine aura.

Migraine Without Aura

Most people with migraine do not experience aura at all — their attacks go directly from the prodrome, if present, into the headache phase. Migraine without aura is diagnosed from the same pattern of headache and accompanying symptoms described above, simply without the preceding neurological symptoms. It is not a milder or less legitimate form of migraine; it is the more common presentation overall.

Types of Migraine

Beyond the basic distinction between migraine with and without aura, a few other patterns are clinically recognized, though the exact terminology can vary:

• Episodic migraine — attacks that occur on fewer days than the threshold used to define chronic migraine (below).
• Chronic migraine — a specific, more frequent pattern described in its own section below.
• Menstrual migraine — attacks linked to the menstrual cycle, discussed further under hormonal migraine below.

Less common, more specific migraine subtypes exist in formal headache classification, but they are relatively rare and are diagnosed by a specialist rather than something to self-identify from an article.

Chronic Migraine

Chronic migraine is a recognized clinical pattern, not simply "migraine that feels worse." The International Classification of Headache Disorders (ICHD-3) defines it as headache occurring on 15 or more days a month for more than three months, where at least 8 of those days a month have the features of a migraine headache. This is a specific diagnostic pattern that a doctor assesses over time, not something to self-diagnose from occasional bad weeks.

Migraine Causes and Risk Factors

Migraine is not caused by one single food or lifestyle factor — it has a genuine neurological and genetic basis. MedlinePlus notes that migraine is more common in women, that it often runs in families, and that it occurs more frequently in people with certain coexisting conditions, including depression, anxiety, and sleep disorders. Having these risk factors makes migraine more likely but does not mean every headache in someone with them is a migraine, and plenty of people with none of these risk factors still develop migraine.

Common Migraine Triggers

Several factors are frequently reported to bring on attacks in people who already have migraine, though triggers vary significantly between individuals and are not scientifically proven to cause migraine in everyone who is exposed to them:

• Sleep disruption, including both too little sleep and, for some people, oversleeping
• Stress, or the period of relaxation right after a stressful stretch
• Skipped or delayed meals
• Dehydration
• Hormonal changes, particularly around menstruation
• Certain foods and drinks, such as alcohol, aged cheese, and processed meats, and caffeine withdrawal — these are commonly reported, individual triggers rather than universal causes
• Bright or flickering lights and strong smells
• Weather or environmental changes, reported by some people

The honest, evidence-based framing is that these factors "may trigger" an attack in someone prone to migraine, not that they reliably cause migraine in everyone.

Migraine and Food

There is no scientifically validated universal "migraine diet," and broad food restriction is not something this guide recommends. What tends to help is eating regular meals rather than skipping them, staying well hydrated, and — if food seems to be a personal trigger — identifying your own specific pattern (often with a headache diary) rather than eliminating many foods at once based on generic lists. Unnecessarily restrictive diets can affect nutrition without a clear benefit if the food in question was never actually a trigger for that individual.

How Migraine Is Diagnosed

Migraine is primarily a clinical diagnosis, based on a person's history and the pattern of their headaches — there is no blood test or scan that confirms migraine on its own. A doctor typically asks about the characteristics of the headache, accompanying symptoms, triggers, and family history, and performs a neurological examination to check for anything unexpected. Imaging such as an MRI or CT scan is not routinely required for typical migraine; it's generally reserved for situations with red-flag features, an atypical pattern, or findings on examination that suggest something other than migraine.

Migraine Treatment

Treatment is generally considered in two separate categories, and people may use one, both, or neither depending on how migraine affects them.

A. Treatment During an Attack (Acute Treatment)

Acute treatment aims to stop or shorten an individual attack already underway. Categories in common clinical use include NSAIDs (such as ibuprofen), acetaminophen/paracetamol, migraine-specific medications called triptans, newer migraine-specific medications called gepants, and anti-nausea medications when nausea or vomiting is prominent. Which option, or combination, is appropriate depends on the individual — their specific symptoms, other health conditions, and medication history — so this is a decision for a doctor, not a recommendation to self-select from this list.

B. Preventive Treatment

Preventive treatment is taken regularly, whether or not a headache is present, to reduce how often attacks occur. It's generally considered when attacks are frequent, severe, or significantly affecting daily life, or when acute treatment alone isn't adequate — a doctor assesses this on an individual basis rather than against a fixed universal rule. Categories include certain blood pressure medications (such as beta-blockers), certain antidepressants, certain anticonvulsant medications, CGRP-targeted therapies (including injectable monoclonal antibodies and oral options), and, for chronic migraine specifically, botulinum toxin injections. Lifestyle measures, discussed below, are a meaningful complement to medication rather than a substitute when preventive treatment is actually needed.

Medication-Overuse Headache

This is an important and often underrecognized issue. Using acute headache medication too frequently can itself lead to more frequent headaches, a cycle called medication-overuse headache. According to the ICHD-3 classification, this is recognized in someone with an existing headache disorder who has headaches on 15 or more days a month, caused by regularly overusing acute medication for more than three months — and the specific frequency that counts as "overuse" differs by medication type: 10 or more days a month for triptans or combination painkillers, and 15 or more days a month for simple painkillers like paracetamol or NSAIDs used alone. The NHS also gives simpler public-facing guidance: try not to take painkillers for headache more than about two days a week, since doing so can itself lead to more headaches. If you find yourself needing acute medication very frequently, that's a reason to discuss preventive treatment with a doctor rather than simply increasing how often you take acute medication.

What to Do During a Migraine Attack

Practical steps that many people find helpful, though not everyone responds the same way:

• Move to a quiet, dark room if possible, since light and sound sensitivity are common
• Stay hydrated
• Take acute medication according to your own prescribed or agreed plan, ideally early in the attack rather than waiting
• Rest, including sleep if you're able to
• Note what preceded the attack, to help identify your own triggers over time

These steps support symptom management; they are not guaranteed to work for everyone, and they don't replace a treatment plan agreed with a doctor.

Migraine Prevention: Lifestyle Tips

Alongside any preventive medication, several lifestyle measures are commonly recommended to reduce attack frequency:

• Keeping a regular sleep schedule
• Eating regular meals rather than skipping them
• Staying well hydrated
• Getting regular exercise as tolerated — some people find certain types of exercise can itself trigger an attack, so this is individual
• Managing stress, through whatever methods work for the person
• Keeping a headache diary to track patterns, potential triggers, and how often attacks occur
• Working with a doctor to identify personal triggers rather than assuming a generic list applies exactly to you

Migraine in Women and Hormonal Migraine

Migraine is more common in women than men, and many women who have migraine notice a link between attacks and their menstrual cycle, often around the time hormone levels drop just before a period — sometimes called menstrual migraine. Migraine can also change during pregnancy: it sometimes improves, particularly later in pregnancy, though this varies and some people find it unchanged or worse. A severe headache that is new or distinctly different, especially later in pregnancy or shortly after giving birth, needs prompt medical attention, since it can occasionally be a sign of a pregnancy-related condition such as preeclampsia rather than an ordinary migraine attack — especially if it comes with vision changes, swelling, or sudden weight gain.

Migraine in Children and Teenagers

Migraine can affect children and teenagers, and the presentation sometimes differs from adults — attacks may be shorter, pain may be felt on both sides of the head rather than one, and digestive symptoms such as abdominal pain or vomiting can be more prominent relative to the headache itself. Because headache patterns in children can also reflect other causes, a new or recurring pattern of headaches in a child or teenager is worth having properly evaluated rather than assumed to be migraine based on an adult's experience.

Migraine vs Other Headaches

Several features can help distinguish migraine from other common headache types, though this is general information, not a way to diagnose yourself:

• Tension-type headache typically causes mild-to-moderate pressing or band-like pain on both sides of the head, usually without the prominent nausea or light sensitivity seen in migraine.
• Cluster headache causes severe pain, usually around one eye, often with that eye watering, redness, or a stuffy nostril on the same side, and people with cluster headache often feel restless and want to move rather than lie still, unlike the stillness many people with migraine seek.
• Ordinary, nonspecific headache is typically milder, doesn't significantly limit activity, and lacks the accompanying features — nausea, light/sound sensitivity, or aura — that characterize migraine.

A doctor, not a symptom list, is the right way to confirm which of these (or another cause entirely) actually explains a particular headache pattern. Our causes of headaches guide covers the broader range of headache causes.

When Migraine May Be an Emergency

It's worth being explicit about the difference: typical migraine aura develops gradually over several minutes, follows a pattern the person may already recognize, and resolves within about an hour. Sudden-onset neurological symptoms, symptoms that don't fit a known pattern, or symptoms accompanied by the red flags above are not typical aura and need prompt assessment rather than waiting to see if it's "just a migraine."

In Jordan, the government portal lists 911 for urgent medical attention and ambulance services, alongside the dedicated ambulance line 193.

When to See a Doctor

See a doctor for headaches that are new, recurring, getting worse, changing in pattern, or significantly affecting daily life or work, even without any of the emergency features above. Getting migraine properly diagnosed, rather than self-managing an assumed migraine indefinitely, is what allows a doctor to consider preventive treatment, rule out other causes, and address medication-overuse headache if it's developed.

Migraine Outlook and Living With Migraine

Migraine is a long-term neurological condition for most people who have it, but it can usually be managed — through some combination of acute treatment, preventive treatment when appropriate, trigger awareness, and lifestyle measures — to meaningfully reduce how much it affects daily life. Treatment is individualized: what works well for one person with migraine may not suit another, which is why ongoing review with a doctor, rather than a fixed one-time plan, tends to give the best results over time.
