Migraine Attacks: Symptoms, Causes, Common Misdiagnoses, and What Actually Helps

Migraine is one of the most common neurological conditions worldwide, yet many people continue to experience symptoms without realizing they may be related to migraine. More than 1 billion people globally live with migraine, and it remains one of the leading causes of disability due to its impact on daily activities, work, and quality of life.

Although migraine is often associated with severe throbbing head pain, the condition can involve a wider range of neurological symptoms. People may experience sensitivity to light or sound, nausea, visual disturbances, difficulty concentrating, fatigue, or changes in how they respond to everyday sensory information.

The challenge is that migraine does not always follow the pattern people expect. Some individuals may not have the classic one-sided headache or dramatic symptoms shown in medical descriptions, which means they may mistake their symptoms for stress, tiredness, sinus problems, or a regular headache.

Recognizing the different ways migraine can present is the first step toward understanding the condition and seeking appropriate care.

What are the main features of a migraine?

Migraine does not look identical in everyone. But most attacks involve a recognizable combination of head pain and neurological symptoms, especially changes in how the brain responds to light, sound, smell, movement, or nausea.

Throbbing or pulsating head pain

Migraine pain is often described as a pulsing, pounding, or throbbing sensation. It commonly affects one side of the head, although some people experience pain on both sides. The pain can range from moderate to severe and may become worse with normal physical activity, such as walking or climbing stairs.

Sensitivity to light, sound, and smells

During an attack, the nervous system becomes unusually sensitive to sensory input. Light, sound, or strong smells that would normally be easy to ignore may suddenly feel overwhelming or painful.

Nausea and other symptoms

Many people experience nausea during a migraine attack, and some may also have vomiting or reduced appetite. Migraine can also affect concentration and energy levels, causing fatigue, difficulty thinking clearly, or a feeling of being mentally drained.

That is an important clue: migraine is more than head pain. It is a neurological event, which is why an attack can affect vision, digestion, concentration, energy, and sensory processing at the same time.

What happens in the brain during a migraine attack?

A migraine attack is not simply a period of head pain. It is a neurological process that develops through different phases, with changes occurring in brain activity, sensory processing, and pain pathways. Not everyone experiences every phase, but understanding these stages helps explain why migraine symptoms can appear before, during, and after the main headache.

Prodrome: early changes before the attack

The prodrome phase can begin hours or even days before the headache phase. During this stage, changes in brain activity and chemical signalling may affect areas involved in mood, energy, appetite, and sensory processing.

Some people may notice:

• Fatigue or low energy
• Mood changes
• Food cravings
• Difficulty concentrating
• Neck stiffness

These symptoms occur because the nervous system is beginning to shift into a migraine state before the pain becomes noticeable.

Aura: temporary changes in brain signalling

Some people experience aura before or during a migraine attack. Aura is caused by temporary changes in electrical activity across the brain, known as cortical spreading depression, which affects areas involved in vision, sensation, or language.

Aura symptoms may include:

• Visual disturbances, such as flashing lights or patterns
• Tingling or numbness
• Difficulty speaking

These symptoms usually develop gradually and resolve completely, often within 5 to 60 minutes.

Headache phase: activation of pain pathways

During the main attack phase, the brain's pain-processing pathways become activated. A key pathway involved is the trigeminovascular system, which connects the trigeminal nerve, blood vessels surrounding the brain, and pain-processing regions.

Activation of this pathway causes the release of signalling molecules, including calcitonin gene-related peptide (CGRP), which increases pain sensitivity and contributes to inflammation-like changes around the nervous system.

This process can lead to:

• Moderate to severe throbbing or pulsating pain
• Nausea or vomiting
• Sensitivity to light, sound, or smells
• Increased discomfort with physical activity

The same changes in sensory processing explain why normal environmental stimuli can become overwhelming during a migraine attack.

Postdrome: recovery after the attack

After the main pain improves, the brain may remain temporarily affected as it returns to its normal state. This recovery phase is sometimes called the "migraine hangover."

During this stage, some people experience:

• Fatigue
• Difficulty concentrating
• Low energy
• Continued sensitivity to sensory input

The duration and intensity of each phase can vary from person to person, which is why migraine attacks do not look identical for everyone.

Why do some people develop migraines?

Genetic factors

There is no single cause of migraine. Instead, some people inherit a nervous system that is more susceptible to migraine, and genetics are an important part of that vulnerability.

Migraine often runs in families. Having a close relative with migraine does not guarantee you will develop it, but inherited factors can lower the threshold at which the nervous system tips into an attack.

Increased sensitivity to pain signals

This lower neurological threshold helps explain why the same trigger can affect two people very differently. A missed meal, bright light, or disrupted night of sleep may do nothing to one person but help push a migraine-prone nervous system toward an attack.

Over time, repeated migraine attacks can affect how the nervous system responds to pain, which may contribute to more frequent or severe episodes in some people.

What can trigger a migraine attack?

A trigger does not cause migraine itself. Think of it as something that can help push an already migraine-prone nervous system past its threshold. That is why triggers vary so much between people, and why identifying your own pattern matters more than following a universal list.

Common triggers include:

• Stress: Emotional stress can increase nervous system sensitivity and make migraine attacks more likely.
• Sleep changes: Too little sleep, too much sleep, or irregular sleep schedules may trigger migraines in some people.
• Hormonal changes: Fluctuations in hormone levels, especially around the menstrual cycle, can contribute to migraine attacks.
• Food and drinks: Skipping meals, dehydration, alcohol, caffeine changes, or certain foods may trigger symptoms for some people.
• Environmental factors: Bright lights, loud sounds, strong smells, and weather changes are commonly reported triggers.
• Physical strain: Intense activity or prolonged exhaustion may increase the chance of an attack.

Keeping track of attacks can make those patterns easier to see. But even if your symptoms fit, how does a clinician decide whether the diagnosis really is migraine?

How is migraine diagnosed?

There is no single blood test or brain scan that confirms migraine. Diagnosis is clinical: a healthcare professional looks at the pattern of your attacks, your medical and family history, and whether the symptoms fit established migraine criteria, shown below.

1. Attack frequency and duration

• You have experienced at least 2 to 5 distinct attacks in your lifetime
• Untreated (or unsuccessfully treated) attacks last between 4 and 72 hours

2. Pain characteristics (must have at least 2 of the following 4)

• Pain is located on one side of the head (unilateral)
• Pain has a throbbing or pulsating quality
• Pain intensity is moderate to severe (disrupts daily activities)
• Pain is worsened by routine movement (e.g., walking, climbing stairs) or causes you to avoid it

3. Associated symptoms (must have at least 1 of the following during an attack)

• Nausea and/or vomiting
• Sensitivity to both light (photophobia) and sound (phonophobia)
• Temporary visual changes (flashes, zig-zag lines, blind spots), numbness/tingling, or speech difficulties, known as aura (if present, usually lasts 5 to 60 minutes before/during pain)

4. Pattern and medical history

• Symptoms are not better explained by another medical condition or secondary headache source
• If you experience headaches on 15+ days per month for over 3 months, with at least 8 of those days matching the migraine features above, you match the criteria for chronic migraine

What other conditions can migraine be confused with?

Migraine symptoms can overlap with other conditions, making it difficult to identify the exact cause without looking at the full symptom pattern.

Tension headaches

Tension-type headache usually causes mild-to-moderate pressing or tightening pain and typically is not aggravated by normal activity. The confusion comes from the fact that migraine is not always one-sided or obviously throbbing, so the overall symptom pattern described above matters more than one feature.

Sinus headaches

Migraine can cause forehead, facial, or pressure-like pain and may even come with nasal symptoms, which is why people often confuse it with a sinus headache.

Up to 80% of self-reported "sinus headaches" are actually migraines, so it is worth reading our article on sinus headaches to rule out whether you may actually be suffering from those instead.

Cluster headaches

Cluster headaches share a similar profile with migraines: people experience one-sided headaches and neurological symptoms such as eye watering, drooping eyelids, light sensitivity and nasal congestion.

These are all symptoms that also occur in severe migraines due to trigeminal nerve pathway activation. Learn more about cluster headaches in our dedicated article.

Medication overuse headaches

Medication overuse almost always develops in someone who already has migraines. As the rebound cycle takes hold, the distinction between a true migraine and a rebound headache blurs into a single, continuous state of pain.

Overuse of triptans or acute pain relievers transforms high-intensity, episodic throbbing pain into a constant, dull, daily ache with periodic spikes, mimicking the exact presentation of chronic migraine.

Sufferers assume their underlying migraine disease is simply worsening or becoming resistant to treatment, rather than recognizing that the acute medications themselves are driving the daily headache baseline.

Get more clarity about your migraine symptoms with Shifia

A misdiagnosis of migraines can mean years of going around in circles with your symptoms, and this happens more often than you think. Migraines are not diagnosed through a specific antibody on a blood test or a finding on a scan. Diagnosis relies upon matching a specific symptom profile as closely as possible. A major problem arises when other conditions also have similar profiles, leaving patients and doctors alike confused.

Shifia's headache assessment chatbot offers a way to assess your symptoms against the full spectrum of headache disorders, and shows you what matches from a particular diagnosis and what does not, helping you to have a much better idea of your condition and ultimately helping you to get to the bottom of that headache you have been suffering with for so long.

Shifia does not replace medical diagnosis, but our free 7 minute questionnaire can certainly help.

What can I do to treat migraines?

Once the pattern makes sense, treatment becomes easier to understand. Migraine care usually has two jobs: stop or reduce an attack that is already happening, and lower the frequency or severity of future attacks.

Medications during a migraine attack

For acute migraine attacks, healthcare providers may recommend medications that target pain, inflammation, and associated symptoms.

These may include:

• Pain relievers: Over-the-counter medications such as ibuprofen, aspirin, naproxen, or acetaminophen may help reduce pain, especially when taken early during an attack.
• Migraine-specific medications: Triptans are designed specifically for migraine treatment and may be recommended when standard pain relievers are not effective. Newer acute treatments, such as gepants, work by blocking CGRP-related pain signalling involved in migraine.
• Anti-nausea medications: These may be used when nausea or vomiting occurs as part of a migraine attack.

Frequent use of acute migraine medications can increase the risk of medication-overuse headaches. People with frequent attacks should discuss their treatment plan with a healthcare professional.

Preventive treatments

Preventive treatments aim to reduce the frequency, severity, or impact of migraine attacks and may be considered when migraines occur frequently or significantly affect daily life.

These may include:

• Blood pressure medications: Certain beta blockers may be used as preventive therapy for some people with migraine.
• Anti-seizure medications: Medicines such as topiramate may help reduce migraine frequency in appropriate patients.
• Antidepressant medications: Some antidepressants may be prescribed for their pain-modulating effects in migraine prevention.
• CGRP-targeted therapies: Newer preventive treatments that target the CGRP pathway may help reduce migraine frequency in suitable patients.
• OnabotulinumtoxinA injections: This treatment may be considered for some adults with chronic migraine.
• Lifestyle approaches: Regular sleep, hydration, stress management, and identifying personal triggers can support migraine management.

How can you reduce the risk of migraine attacks?

Prevention does not always mean eliminating migraine completely. The goal is usually to reduce how often attacks happen, how severe they become, and how much they disrupt your life. A consistent routine can help lower your migraine threshold.

• Maintain a regular sleep schedule.
• Stay hydrated and avoid skipped meals.
• Manage stress through relaxation techniques.
• Keep track of migraine patterns and possible triggers.

A headache diary can also help you spot patterns in sleep, meals, stress, hormones, medication use, and other possible triggers. If attacks remain frequent or disabling despite lifestyle measures, a healthcare professional can discuss whether preventive treatment should become part of your plan.

When should you seek medical advice?

Most migraine attacks are not dangerous. But once you know your usual pattern, a major change deserves attention rather than being automatically written off as "just another migraine."

Seek medical advice if:

• Increasing frequency or severity: Your migraines become more frequent, more intense, or different from your usual pattern.
• Impact on daily activities: Migraine attacks begin interfering with work, routine activities, or quality of life.
• New neurological symptoms: You experience new weakness, numbness, confusion, difficulty speaking, or vision changes that are different from your typical migraine symptoms.
• Reduced treatment effectiveness: Your usual migraine treatments are no longer providing adequate relief.

A healthcare provider can review your symptoms, rule out other causes, and recommend the most suitable management approach.

Living with migraine is easier with the right support
