Migraine Symptoms: Early Signs, Symptoms & Warning Signs

Quick Glance: Common Migraine Symptoms

Common migraine symptoms may include:

Moderate to severe throbbing or pulsating headache, often on one side of the head
Sensitivity to light (photophobia)
Nausea or vomiting
Sensitivity to sound (phonophobia)
Visual aura, such as flashing lights, zigzag lines or temporary blind spots
Tiredness or unusual fatigue
Difficulty concentrating
Neck stiffness or discomfort

Symptoms of Migraine That Should Not Be Ignored

Some symptoms may indicate the worsening of migraine condition or cause serious complications that require timely medical evaluation. Migraine symptoms that should not be ignored are:

Symptom	What It May Indicate
Headache lasting more than 72 hours	A prolonged, debilitating attack may be status migrainosus and requires medical assessment.
Aura symptoms lasting longer than an hour	May require assessment to rule out other neurological causes, particularly if the symptoms differ from previous attacks.
Increasing frequency of attacks	May indicate a change that needs medical evaluation.
Vomiting leading to dehydration	May lead to dehydration and may require medical care.
New headache pattern after age 50	New headaches later in life should be assessed for possible secondary causes.
Headache that worsens with coughing or straining	May have causes other than migraine and should be medically assessed.

Why Do Migraine Symptoms Occur?

Migraine symptoms occur because of temporary changes in brain activity and the way the nervous system processes pain and sensory signals. The trigeminal nerve system plays an important role in migraine pain, while chemical messengers such as CGRP (calcitonin gene-related peptide) can contribute to inflammation and pain signalling.

In migraine with aura, temporary changes in brain activity can produce reversible visual, sensory or speech symptoms. Other symptoms, such as nausea and sensitivity to light or sound, are also linked to changes in how the nervous system processes sensory signals. Hormonal changes, stress, disrupted sleep, dehydration and missed meals may trigger attacks in some people, but triggers vary between individuals.

Migraine Symptoms That Require Immediate Medical Attention

Seek emergency medical attention for migraine symptoms such as:

A sudden, extremely severe headache that reaches maximum intensity within minutes
Sudden weakness or numbness, especially on one side of the body
Difficulty speaking, understanding speech, walking or maintaining balance
Loss of consciousness or a seizure
New or persistent vision loss or double vision
Severe confusion or a marked change in alertness
Fever with a stiff neck or severe headache
A severe headache following a significant head injury

Symptoms of Migraine Based on Type

Migraine occurs in a number of forms, and the symptoms may differ according to the type. The table below shows the recognised types of migraine and their typical symptoms:

Type of migraine	Typical symptoms
Migraine without aura	Moderate to severe headache, nausea or vomiting, sensitivity to sound or light, throbbing or pulsating.
Migraine with aura	Temporary visual, sensory or speech or language symptoms that usually develop gradually and may occur before or during the headache.
Chronic migraine	Headache occurring on 15 or more days a month for more than 3 months, with migraine features on at least 8 days a month.
Hemiplegic migraine	Migraine aura that includes temporary motor weakness, along with reversible visual, sensory or speech symptoms.
Migraine with brainstem aura	Reversible symptoms such as tinnitus, vertigo, double vision, reduced hearing, poor coordination or reduced consciousness, without motor weakness.

Symptoms of Migraine-Specific Conditions

Below are the migraine-associated conditions with their symptoms:

Condition	Typical symptoms
Menstrual-related migraine	Migraine attacks during menstruation, usually with headache, nausea, vomiting and light or sound sensitivity; attacks may be longer or more severe.
Migraine aura without headache	Temporary visual changes, numbness or speech difficulties, pins and needles, without a subsequent headache.

Symptoms of Migraine in Women

The migraine symptoms are generally similar in men and women. However, hormonal fluctuations can influence migraine attacks in some women, particularly around menstruation. Below are the symptoms of migraine that develop in women:

Throbbing or pulsating headache
Nausea or vomiting
Sensitivity to light and sound
Temporary aura symptoms, such as visual changes or pins and needles
Migraine attacks around menstruation

Symptoms of Migraine in Children

Migraines can affect children, and their symptoms may vary from those commonly appearing in adults. Children may experience pain on both sides of the head, and attacks may be shorter than in adults. The common symptoms of migraine in children include:

Moderate to severe headache
Nausea or vomiting
Sensitivity to light or sound
Dizziness or light-headedness
Visual changes
Difficulty concentrating
Irritability or tiredness
Abdominal pain in some children

Can You Have Migraines Without Symptoms?

Yes. You can have a migraine without a headache. This condition is called a silent or acephalgic migraine. This may occur in migraine with aura without headache.

In some cases, people also go through a premonitory phase one or two days before the attack, during which they experience mild symptoms such as changes in mood, a craving for food, or neck stiffness.

In other cases, individuals may experience the quiet 'postdrome' phase after the headache has passed. This phase is marked by tiredness or difficulty concentrating and is called a migraine hangover.

When Do Migraine Symptoms Become Life-Threatening?

Migraine is not a life-threatening health condition, but severe symptoms can indicate serious medical conditions. Unusual or sudden symptoms should not be ignored and require immediate medical assessment. Below are the symptoms of migraine that may become life-threatening:

Emergency symptom	Why it needs urgent attention
Sudden, extremely severe headache	A headache that reaches maximum intensity within minutes can occur with serious conditions such as bleeding around the brain.
Sudden weakness or numbness	New weakness or numbness, particularly on one side of the body, may indicate a neurological emergency such as a stroke.
Difficulty speaking or understanding speech	New speech or language problems need urgent assessment.
Loss of consciousness or seizure	These are not typical features of an ordinary migraine and may indicate another neurological problem.
Severe confusion	Sudden confusion or a major change in alertness requires urgent assessment.
Headache with fever and stiff neck	This combination can occur with meningitis or another serious infection.
Sudden or persistent vision loss	Vision loss may have causes other than migraine aura and needs urgent assessment.
Headache after a significant head injury	A headache following significant head trauma may indicate an injury requiring urgent evaluation.

How are Migraine Symptoms Diagnosed?

There is no single blood test that confirms migraine. The diagnosis is based primarily on the type of symptoms and other possible causes of headache, especially when the pattern is new or unusual. Migraine is usually diagnosed based on symptoms, medical history and the following examinations:

Diagnostic Test	Purpose
Neurological examination	Checks for neurological abnormalities and helps identify signs that may suggest another cause of headache.
Medical history and symptom assessment	Helps identify the headache pattern, associated symptoms, duration, frequency and possible triggers.
MRI or CT scan	May be recommended when symptoms are unusual, the neurological examination is abnormal, or there are other concerns about a secondary cause of headache.
Headache diary	Records headache frequency, duration, severity, associated symptoms and possible triggers to support diagnosis.
