Migraine vs Headache: How to Tell the Difference and When to See a Doctor
By Apex Hospitals, 13th April, 2026 5 min read
Most people have used the words 'headache' and 'migraine' interchangeably at some point. But they are not the same condition. A migraine is a neurological disorder, one that can be severely disabling, while a headache is often a symptom with a much simpler cause.
Getting this distinction right matters, because the way you manage a headache and the way you manage a migraine are quite different. Taking the wrong approach can either provide no relief or make things worse.
This article breaks down the differences clearly, and explains when it is time to stop self-managing and see a doctor.
What Is a Headache?
A headache refers to pain anywhere in the head or neck region. The most common type is a tension headache, a dull, pressing or tightening sensation that feels like a band around the head. It typically affects both sides, is mild to moderate in intensity, and does not usually interfere significantly with daily activity.
Common causes of tension headaches include:
• Stress and anxiety
• Poor posture, especially from long hours at a desk or on a screen
• Dehydration
• Eye strain
• Skipped meals or low blood sugar
• Lack of sleep
Tension headaches usually respond well to over-the-counter painkillers like paracetamol or ibuprofen, rest, and hydration. They pass within a few hours and leave no lasting effects.
What Is a Migraine?
A migraine is a neurological condition characterized by recurring episodes of moderate to severe head pain, usually throbbing, often on one side of the head, accompanied by a range of other symptoms that a regular headache simply does not produce.
Migraines can last anywhere from 4 hours to 3 days. During an attack, many people are unable to carry on with normal activities. They need to lie down in a dark, quiet room and wait for the episode to pass.
Migraines are not caused by stress or dehydration alone, they involve changes in brain chemistry, nerve signaling, and blood flow. They tend to run in families, are more common in women, and often begin in adolescence or early adulthood.
The Four Phases of a Migraine
Unlike a headache, a migraine often follows a pattern with distinct phases:
• Prodrome (hours to days before): Mood changes, food cravings, neck stiffness, frequent yawning, or increased thirst
• Aura (not always present): Visual disturbances such as flashing lights, blind spots, or zigzag lines; tingling in the face or hands; difficulty speaking
• Attack: Throbbing or pulsating head pain, nausea, vomiting, extreme sensitivity to light, sound, and smell
• Postdrome (after the attack): Fatigue, confusion, or a 'washed out' feeling that can last up to a day
Migraine vs Headache: The Key Differences at a Glance
Headache | Migraine | |
| Pain Character | Pressure-like or tightening, as if the head is being squeezed | Throbbing or pulsating, often described as a heartbeat inside the head |
| Location | Usually both sides of the head | Typically one side, can shift or affect both sides in some cases |
| Severity | Mild to moderate — unpleasant but manageable | Moderate to severe — often disabling; many cannot work or function normally |
| Duration | 30 minutes to a few hours | 4 hours to 72 hours without treatment |
| Associated Symptoms | Rarely accompanied by nausea, vomiting, or light/sound sensitivity | Nausea and vomiting are common; sensitivity to light and sound are hallmark features |
| Aura | None | About 1 in 3 people experience aura — visual or sensory disturbances before or during the attack |
| Response to Medication | Usually responds to standard OTC painkillers | Often needs specific medication (triptans) or preventive therapy |
What Triggers a Migraine?
Migraines are often triggered by specific factors. Identifying and avoiding personal triggers is one of the most effective ways to reduce attack frequency. Common triggers include:
• Hormonal changes — particularly in women around menstruation, pregnancy, or menopause
• Disrupted sleep — too much or too little
• Skipping meals or fasting
• Certain foods and drinks — aged cheese, processed meats, alcohol (especially red wine), caffeine
• Strong sensory input — bright lights, loud noise, strong smells
• Weather changes — drop in barometric pressure
• High stress or sudden relief from stress
• Dehydration
Keeping a migraine diary, noting when attacks happen, how long they last, and what preceded them, can help identify your personal triggers and is very useful when consulting a neurologist.
When Should You See a Doctor?
Many people manage occasional headaches on their own without ever needing a doctor. But there are specific situations where medical evaluation is necessary, and others where it is urgent.
Book an Appointment with a Neurologist If:
• You get headaches more than 4 times a month
• Your headaches are getting more frequent or more severe over time
• OTC painkillers are no longer working as well as they used to
• Headaches are affecting your ability to work, sleep, or carry out daily activities
• You experience aura or unusual visual symptoms before a headache
• You suspect your headaches may be migraines but have never been formally diagnosed
• You are taking painkillers very frequently, this can itself cause a type of headache called medication overuse headache
Go to Emergency Immediately If You Have:
• A sudden, extremely severe headache that feels like the worst of your life — especially if it came on within seconds
• A headache with fever, stiff neck, and sensitivity to light (possible meningitis)
• Headache with confusion, slurred speech, or weakness on one side of the body (possible stroke)
• Headache after a head injury
• A headache that wakes you from sleep and is progressively worsening
How Are Migraines Diagnosed and Treated?
There is no single test for migraine. Diagnosis is based on a detailed history of symptoms, frequency, duration, and associated features. A neurologist may recommend investigations such as an MRI or CT scan to rule out other causes, particularly if the headache pattern is new or unusual.
Treatment Options
Migraine treatment falls into two categories:
• Acute treatment — taken at the onset of an attack to stop or reduce it. This includes triptans, anti-nausea medications, and in some cases, specific newer medications called CGRP antagonists.
• Preventive treatment — taken regularly to reduce the frequency and severity of attacks. This includes certain blood pressure medications, antidepressants, anti-seizure drugs, and CGRP-targeted injections.
Lifestyle modifications — managing sleep, diet, hydration, and stress, play an important supporting role alongside medication.
The Bottom Line
A headache and a migraine are two different things, and they deserve different responses. If your headaches are frequent, severe, or disrupting your life, that is not something to simply push through. It is something to address with the right medical support.
A neurologist can confirm whether what you are experiencing is migraine, identify your triggers, and put together a treatment plan that actually works, rather than reaching for painkillers every time and hoping for the best.
At Apex Hospitals, our neurology team sees patients with all types of headache disorders and provides structured, evidence-based care. If headaches are becoming a pattern in your life, it is worth getting them properly assessed.
