Migraine is one of those conditions that gets dismissed far too often, written off as “just a bad headache” by people who have never experienced one. As a pharmacist, I want to set the record straight: migraine is a complex neurological condition, and for millions of people, it is genuinely disabling.
The word “migraine” comes from the Greek hemicrania, meaning “half the head”, a nod to the one-sided head pain that many sufferers experience. But migraine is far more than head pain. It is a disorder of the brain and nervous system that can affect vision, speech, movement, digestion, mood, and sensory perception. An attack can last anywhere from a few hours to several days, and the effects can linger even after the worst of it has passed.
If you have been wondering whether what you experience is migraine, or you simply want to understand the condition better, this guide covers everything you need to know, from the first warning signs to when it is time to see a doctor. If this sounds familiar, you’re not alone, migraine symptoms are often misunderstood or overlooked.
How Common Is Migraine?
Migraine is remarkably common worldwide. The Global Burden of Disease Study consistently ranks it among the top causes of disability globally, affecting an estimated one billion people. In the UK, around one in seven people live with migraine, making it more prevalent than diabetes, epilepsy, and asthma combined. Globally, it is the second leading cause of years lived with disability, according to the World Health Organization.
Despite this, migraine remains significantly underdiagnosed and undertreated. Many people manage their symptoms for years without ever receiving a formal diagnosis, either because they normalize the pain or because they do not realize that what they have is a recognized medical condition with effective treatments.
The Four Phases of a Migraine Attack
One of the defining features of migraine, and something that separates it clearly from ordinary headache, is that it typically unfolds in distinct phases. Not everyone experiences all four, and the intensity varies between individuals and even between attacks in the same person.
• Prodrome (the warning phase)
Up to 24 to 48 hours before the headache begins, many people notice subtle changes that signal an attack is coming. These prodrome symptoms can include mood shifts (often irritability or unusual euphoria), food cravings, increased yawning, fatigue, neck stiffness, and heightened sensitivity to light or sound. Recognizing these early migraine symptoms can help you take action before the attack fully develops.
• Aura
Roughly one in three people with migraine experience aura, a series of neurological symptoms that typically develop gradually over five to twenty minutes and last up to an hour. Visual aura is the most common type: people describe zigzag lines, flickering lights, blind spots, or tunnel vision. Some experience sensory aura, such as tingling or numbness spreading from the fingers up the arm or across the face. In rarer cases, aura can temporarily affect speech.
It is important to know that aura symptoms are temporary and fully reversible. However, if you experience sudden neurological symptoms for the first time, especially one-sided weakness, speech loss, or vision changes, you should seek urgent medical attention to rule out stroke.
• Headache phase
This is the phase most people associate with migraine. The pain is typically moderate to severe, often throbbing or pulsating, and in many cases affects one side of the head, though it can be bilateral. Physical activity tends to worsen it significantly. Nausea and vomiting are common, as is extreme sensitivity to light (photophobia), sound (phonophobia), and sometimes smell. During this phase, most people find that all they can do is lie still in a dark, quiet room.
This phase can last anywhere from four hours to 72 hours if untreated. This is where migraine differs sharply from a typical headache, the intensity and associated symptoms can make normal functioning nearly impossible.
• Postdrome (the recovery phase)
Often called the “migraine hangover,” the postdrome follows the resolution of the headache. People frequently describe feeling exhausted, mentally foggy, emotionally drained, and physically weak. Concentration is difficult, and some people feel a lingering sensitivity to light. This phase can last 24 to 48 hours and is often underappreciated by those who have not experienced it.
Migraine vs an Ordinary Headache, Key Differences
This is a question I am asked regularly, and the distinction genuinely matters, because the two conditions are managed very differently.
A tension type headache, the most common form of ordinary headache, typically produces a dull, pressing, band like pain around the head. It is usually mild to moderate in severity, does not worsen with movement, and is not accompanied by nausea or significant light and sound sensitivity. Most people can carry on with their day, even if uncomfortable.
Migraine, by contrast, tends to be significantly more intense, is often one-sided, and is associated with a cluster of accompanying symptoms, nausea, vomiting, and sensory hypersensitivity being the most telling. Physical activity makes it worse rather than better. The attack has a recognizable pattern and timeline. And crucially, migraine interferes with the ability to function, most sufferers cannot work, drive, or care for others during an attack.
If your headache is severe enough to stop you in your tracks, comes with nausea or light sensitivity, and follows a recognizable pattern, it is worth discussing migraine with your doctor or pharmacist. Understanding how to tell if it’s a migraine is the first step toward getting the right treatment.
Types of Migraine
Migraine is not a single, uniform condition. There are several distinct types, each with its own characteristics.
Migraine without aura is the most common form, accounting for around 70 to 75 percent of cases. It follows the four-phase pattern described above but without the neurological aura symptoms before the headache.
Migraine with aura affects roughly 25 to 30 percent of people with migraine. The headache phase is preceded by the visual, sensory, or speech disturbances described earlier. Research published in journals including Cephalalgia and Headache has explored whether migraine with aura carries slightly different cardiovascular risk implications compared with migraine without aura, this is a conversation worth having with your healthcare provider, particularly if you smoke or take combined hormonal contraceptives.
Silent migraine (or acephalgic migraine) is a form in which a person experiences the aura, including visual disturbances, sensory changes, or cognitive symptoms, but without the headache phase. This can be alarming if you do not know what it is, particularly when visual symptoms are involved.
Vestibular migraine is increasingly recognized as a significant subtype, causing episodes of vertigo, dizziness, and balance problems, which may or may not be accompanied by head pain. It is one of the more common causes of episodic vertigo in adults and is often misdiagnosed for years.
Menstrual migraine affects many women in the days around their period, typically in the two days before or the first three days of menstruation. This is thought to be driven by the sharp drop in oestrogen that occurs at this time. Menstrual migraines are often particularly severe and tend to last longer than attacks at other times of the cycle.
Chronic migraine is defined as experiencing headache on 15 or more days per month for more than three months, with at least eight of those days meeting criteria for migraine. It is a significant clinical category associated with greater disability and quality of life impact.
Who Is Most Affected?
Migraine affects people across all ages, ethnicities, and geographies, but it is not equally distributed.
Women are two to three times more likely to experience migraine than men, a disparity that emerges after puberty and narrows again after the menopause. This strongly points to hormonal influences, particularly fluctuating oestrogen levels, as a key driver. Pregnancy, the menstrual cycle, perimenopause, and hormonal contraception can all affect migraine frequency and severity.
Genetics also plays a meaningful role. Research suggests that if one parent has migraine, a child has roughly a 50 percent chance of developing it. If both parents are affected, that risk rises to around 75 percent. Studies have identified several genetic variants associated with migraine susceptibility, particularly in genes involved in neuronal excitability and ion channel function.
Migraine most commonly peaks in people aged 25 to 55, overlapping significantly with working-age adults, which partly explains the substantial economic and workplace impact of the condition globally.
When to See a doctor
Most migraines are not dangerous, but some symptoms should never be ignored.
Many people live with migraine for years without a formal diagnosis. If you regularly experience moderate to severe headaches that interfere with your daily life, especially if accompanied by nausea or light and sound sensitivity, it is absolutely worth speaking to your healthcare provider. Migraine is a diagnosable, treatable condition, and you do not have to simply push through it.
There are also circumstances that require urgent medical attention. Seek emergency care if you experience any of the following,
A sudden, severe headache unlike anything you have felt before, sometimes described as a “thunderclap” headache, which comes on within seconds and reaches peak intensity almost immediately. This can be a warning sign of a serious brain condition and must be assessed immediately.
A headache accompanied by fever, a stiff neck, a rash, confusion, or sensitivity to light that is not part of your usual migraine pattern, these can be signs of meningitis or other conditions requiring urgent treatment.
Neurological symptoms such as weakness on one side of the body, slurred speech, or sudden vision loss, particularly if these are new or different from your usual aura.
These symptoms overlap with those of stroke and require immediate emergency medical attention without delay.
Headache following a head injury.
A significant change in the pattern, frequency, or character of your headaches, particularly in someone over the age of 50.
How Is Migraine Diagnosed?
There is no blood test or brain scan that confirms migraine. Diagnosis is clinical, meaning it is based on a careful review of your symptoms, their pattern, duration, and associated features. Doctors typically use criteria established by the International Headache Society (IHS), which are used globally as the standard framework for diagnosis.
Your health care provider or neurologist will ask about the frequency and character of your headaches, any associated symptoms, your medical history, and any family history of migraine. Investigations such as MRI scanning are not routinely needed for typical migraine but may be arranged if there are atypical features or red flag symptoms that need to be ruled out.
Keeping a headache diary in the weeks before your appointment is genuinely valuable. Recording the date, duration, severity, associated symptoms, possible triggers, and any medication taken gives your doctor a much clearer picture and can significantly speed up the diagnostic process.
The Wider Impact of Migraine
Migraine is not just a personal health problem, it has a wide-reaching impact on quality of life, mental health, and society as a whole.
For individuals, the effects extend well beyond the attack itself. People with frequent migraines often report anxiety about when the next attack will strike, leading to social withdrawal, reduced participation in work and family life, and difficulties in maintaining relationships.
The unpredictability of the condition is one of its most distressing aspects. For many people, it is not just the pain but the uncertainty that affects daily life.
There is a well-established bidirectional relationship between migraine and mental health conditions. Research has found that people with migraine are significantly more likely to experience depression and anxiety than those without it, and that the relationship runs in both directions, meaning that depression and anxiety can also increase migraine risk. Addressing mental health as part of migraine management is therefore not optional; it is essential.
In the workplace, migraine is a leading cause of lost productivity. Globally, its economic impact, driven by absenteeism and reduced performance at work (presenteeism), is estimated to run into the hundreds of billions of dollars each year.
For the NHS and health systems worldwide, migraine represents a significant burden. It accounts for millions of healthcare visits, emergency department visits, and neurology referrals annually. Despite being so prevalent, investment in migraine research and specialist services has historically lagged behind other neurological conditions of similar burden.
A Final Word
Understanding migraine is the first step toward managing it effectively.
Migraine is a real, clinically recognized neurological condition. It is not exaggeration, low pain tolerance, or an excuse. For the people who live with it, and there are hundreds of millions of them worldwide, it can be a defining and limiting feature of daily life.
The good news is that understanding has grown significantly in recent years. There are more treatment options available now than ever before, including newer preventive therapies specifically developed for migraine. From lifestyle changes to targeted migraine treatment options, effective management is possible with the right approach.
If you suspect you have migraine, start that conversation with your healthcare provider or pharmacist. You deserve an accurate diagnosis and a treatment plan that actually works.
FAQs
Q1. What is the difference between a migraine and a tension headache?
A tension headache typically causes a dull, pressing pain around both sides of the head, is mild to moderate in severity, and does not usually stop you from going about your day. A migraine is a neurological condition that produces moderate to severe, often one-sided, throbbing pain accompanied by nausea, vomiting, and sensitivity to light and sound. Physical activity makes migraine worse, and most people cannot function normally during an attack. If your headaches are regularly disrupting your life, speak to your health care provider pharmacist.
Q2. Can migraine occur without a headache?
Yes, Silent migraine, also known as acephalgic migraine, involves the neurological symptoms of a typical migraine attack, such as visual disturbances, tingling, or cognitive changes, without any head pain. This can be confusing and alarming if you do not know what it is. If you experience unexplained episodes of visual disturbances or sensory changes, see your doctor for an assessment.
Q3. What triggers a migraine attack?
Triggers vary between individuals, but commonly reported ones include hormonal changes (particularly around menstruation), stress, disrupted sleep, dehydration, skipping meals, bright or flickering lights, strong smells, alcohol (especially red wine), and certain foods such as aged cheese or processed meats.
Keeping a headache diary can help you identify your personal triggers over time.
Q4. Is migraine hereditary?
There is a strong genetic component to migraine. If one parent has migraine, a child has approximately a 50 percent chance of developing it. If both parents are affected, that risk rises to around 75 percent. Having a family history of migraine does not mean attacks are inevitable, but it does mean you are more likely to be susceptible.
Q5. How is migraine treated?
Migraine treatment falls into two broad categories: acute treatment, which aims to relieve symptoms during an attack, and preventive treatment, which aims to reduce how often attacks occur. Acute options include over the counter pain relief such as ibuprofen or paracetamol, anti-nausea medication, and prescription triptans. Preventive options range from certain blood pressure medications and antidepressants to newer CGRP-targeted therapies. Your healthcare provider or neurologist can advise on the right approach for your situation.
Q6. When should I seek emergency care for a headache?
Seek emergency care immediately if you experience a sudden, extremely severe headache that comes on within seconds, often described as the worst headache of your life. Also seek urgent help if your headache is accompanied by fever, neck stiffness, a rash, confusion, one-sided weakness, slurred speech, or sudden vision loss. These symptoms can indicate serious conditions such as meningitis or stroke that require immediate treatment.
Q7. Does migraine affect mental health?
Yes, and the relationship runs in both directions. People with migraine are significantly more likely to experience depression and anxiety, and those conditions can in turn increase the frequency and severity of migraine attacks. If you are struggling with your mental health alongside your migraines, it is important to discuss both with your doctor, as addressing one can positively affect the other.
Q8. Can children get migraines?
Yes, Migraine can begin in childhood and is more common in boys before puberty, after which the pattern shifts and women become disproportionately affected. In children, migraine may present differently, attacks are often shorter, and the headache may be on both sides rather than one. Abdominal pain, nausea, and vomiting can be prominent features. If your child regularly experiences severe headaches that disrupt school or daily life, speak to your healthcare provider.
