Migraine vs. Headache: When Should You Seek Care?

An Evidence-Based Guide from Emcura Medical Clinic

By a Board-Certified Family & Integrative Medicine Physician

Almost everyone experiences a headache at some point. For many people, the cause is relatively simple—stress, dehydration, lack of sleep, illness, eye strain, or muscle tension. But some headaches are migraines, and occasionally a new or severe headache can signal a medical condition requiring urgent or emergency evaluation.

Understanding the difference between a typical headache and migraine can help you choose the right treatment and recognize important warning signs.

At Emcura Medical Clinic, we evaluate headaches by considering the pattern of pain, associated symptoms, medical history, medications, lifestyle factors, and potential red flags. Our goal is not simply to relieve the pain, but to determine why the headache is occurring and whether additional testing or treatment is necessary.

What Is a Headache?

A headache is pain or discomfort involving the head, scalp, face, or upper neck.

There are many different types of headaches. Some are primary headaches, meaning the headache itself is the medical condition. Others are secondary headaches, meaning another condition is causing the pain.

Common primary headache disorders include:

• Tension-type headaches

• Migraine

• Cluster headaches

Secondary headaches may be associated with:

• Viral illness

• Sinus or respiratory infections

• Dehydration

• Medication effects

• Head injury

• Very high blood pressure

• Other medical or neurologic conditions

Most headaches are not dangerous, but the pattern and accompanying symptoms matter.

Tension Headache vs. Migraine

Two of the most common headache types are tension-type headaches and migraines.

Not every migraine follows the classic pattern, and not every severe headache is a migraine.

What Does a Migraine Feel Like?

Migraine is a neurologic disorder that can cause much more than head pain.

Symptoms may include:

• Moderate to severe headache

• Throbbing or pulsating pain

• Pain on one or both sides of the head

• Nausea

• Vomiting

• Sensitivity to light

• Sensitivity to sound

• Sensitivity to smells

• Dizziness

• Difficulty concentrating

• Fatigue

Physical activity may worsen symptoms, and many patients prefer to rest in a quiet, dark room during an attack.

Migraines may last for several hours or, without effective treatment, sometimes longer.

What Is a Migraine Aura?

Some people experience migraine with aura.

Aura usually occurs before or during a migraine and may cause temporary neurologic symptoms.

Visual symptoms are most common and may include:

• Flashing lights

• Zigzag lines

• Shimmering spots

• Blind spots

• Changes in vision

Other aura symptoms can include:

• Tingling

• Numbness

• Difficulty speaking

Because symptoms such as new weakness, numbness, speech difficulty, or vision loss can also occur with stroke and other neurologic emergencies, new or unusual neurologic symptoms should not automatically be assumed to be migraine.

What Is a Tension Headache?

Tension-type headaches commonly feel like:

• Pressure around the forehead

• Tightness around the head

• A band-like sensation

• Tenderness in the scalp, neck, or shoulders

They are often associated with:

• Stress

• Poor posture

• Muscle tension

• Fatigue

• Prolonged computer use

• Lack of sleep

Unlike migraine, tension headaches typically do not cause significant nausea or vomiting and are less likely to worsen with routine physical activity.

Common Migraine Triggers

Migraine triggers vary from person to person.

Common triggers may include:

• Stress

• Poor sleep

• Changes in sleep schedule

• Dehydration

• Skipping meals

• Alcohol

• Hormonal changes

• Bright lights

• Strong smells

• Weather changes

• Certain foods in susceptible individuals

• Excess caffeine

• Caffeine withdrawal

Keeping a headache diary can help identify patterns.

Hormones and Migraines

Hormonal changes can play an important role in migraines, particularly in women.

Migraines may occur or change:

• Around menstruation

• During pregnancy

• After pregnancy

• During perimenopause

• Around menopause

• After starting or stopping certain hormonal medications

Changes in estrogen levels may influence migraine frequency and severity.

Patients with migraine with aura should discuss hormonal contraceptive and hormone therapy choices with their healthcare provider because individual vascular risk factors may affect treatment decisions.

Can Dehydration Cause Headaches?

Yes.

Even mild dehydration may trigger headaches in some people.

Headaches related to dehydration may be accompanied by:

• Thirst

• Dry mouth

• Dark urine

• Fatigue

• Dizziness

Regular fluid intake is particularly important during exercise, illness, travel, and hot weather.

Can Lack of Sleep Cause Migraines?

Yes.

Both too little sleep and significant changes in sleep schedule can trigger headaches and migraines.

Helpful habits include:

• Maintaining a consistent bedtime

• Getting adequate sleep

• Limiting late-night screen exposure

• Avoiding excessive caffeine late in the day

• Treating underlying sleep disorders when present

Patients with frequent morning headaches may also need evaluation for conditions such as sleep apnea.

Can High Blood Pressure Cause a Headache?

Mild or moderately elevated blood pressure usually does not cause obvious headache symptoms.

However, severely elevated blood pressure—particularly when accompanied by signs of acute organ injury—can be associated with:

• Severe headache

• Chest pain

• Shortness of breath

• Vision changes

• Confusion

• Neurologic symptoms

These symptoms require prompt medical evaluation.

Is It Really a Sinus Headache?

Many headaches attributed to “sinus pressure” may actually be migraines.

Migraine can sometimes cause:

• Facial pressure

• Nasal congestion

• Watery eyes

• Pain around the forehead or cheeks

A true sinus infection is more likely when headache or facial pressure occurs along with symptoms such as persistent nasal symptoms, fever, or other findings suggesting acute sinusitis.

Repeatedly treating presumed “sinus headaches” without evaluating for migraine may delay effective treatment.

How Are Migraines Treated?

Migraine treatment depends on:

• Frequency

• Severity

• Associated symptoms

• Medical history

• Other medications

• How much migraines interfere with daily life

Treatment generally falls into two categories.

Acute Treatment

These treatments are taken during a migraine attack.

Depending on the patient, options may include:

• Acetaminophen

• NSAIDs such as ibuprofen or naproxen

• Triptans

• CGRP-targeting medications

• Anti-nausea medications

• Other prescription migraine therapies

Early treatment often works better than waiting until the migraine becomes severe.

Preventive Treatment

Preventive treatment may be considered when migraines are frequent, disabling, prolonged, or difficult to control.

Options may include:

• Certain blood pressure medications

• Certain seizure medications

• Certain antidepressants

• CGRP-targeting medications

• Botulinum toxin injections for appropriate patients with chronic migraine

Treatment should be individualized.

Lifestyle Strategies for Migraine Prevention

Lifestyle habits can significantly influence migraine frequency.

We encourage patients to focus on consistency.

Helpful strategies include:

• Regular sleep

• Adequate hydration

• Regular meals

• Routine exercise

• Stress management

• Limiting excessive caffeine

• Avoiding known personal triggers

• Keeping a headache diary

The goal is not necessarily to eliminate every possible trigger, but to identify patterns that consistently affect you.

Are Supplements Helpful for Migraine Prevention?

Some supplements have been studied for migraine prevention, including:

• Magnesium

• Riboflavin (vitamin B2)

• Coenzyme Q10

Evidence and appropriate dosing vary, and supplements can interact with medications or be inappropriate for certain patients.

Discuss supplements with your healthcare provider before starting them, particularly if you are pregnant, have kidney disease, or take prescription medications.

Be Careful With Too Much Headache Medication

Frequent use of acute headache medications can sometimes contribute to medication-overuse headache.

This can occur with repeated use of certain:

• Acetaminophen-containing medications

• NSAIDs

• Combination headache medications

• Triptans

• Other acute migraine medications

If you are frequently reaching for headache medication, it may be time to discuss a preventive strategy with your healthcare provider.

When Should You Visit Urgent Care for a Headache?

Consider medical evaluation if you have:

• A new headache that is unusual for you

• A headache that is worsening

• Persistent headache

• Recurrent headaches affecting daily life

• Migraine symptoms that are not responding to your usual treatment

• Significant nausea or vomiting

• Headache associated with a respiratory illness or dehydration

• Headache after a minor injury

• Concerns about your blood pressure

• Increasing headache frequency

• A significant change in your usual headache pattern

Urgent care can help determine whether symptoms are consistent with a common headache disorder or whether further evaluation is necessary.

When Is a Headache an Emergency?

Certain headache symptoms require immediate emergency evaluation.

Seek emergency medical care for:

• A sudden, extremely severe headache that reaches maximum intensity rapidly

• A severe headache described as the “worst headache of your life”

• New weakness or numbness

• Facial drooping

• Difficulty speaking

• New confusion

• Loss of consciousness

• Seizure

• New significant vision loss

• Severe headache after significant head trauma

• Headache with high fever and neck stiffness

• Headache with persistent vomiting and neurologic changes

• Severe headache during pregnancy or the postpartum period

• A new severe headache in someone who is significantly immunocompromised

These symptoms may indicate conditions requiring rapid diagnosis and treatment.

What Is a Thunderclap Headache?

A thunderclap headache is a severe headache that begins suddenly and reaches maximum intensity within seconds to about a minute.

It can sometimes indicate bleeding around the brain or another serious vascular problem.

A first-time thunderclap headache requires emergency evaluation, even if the pain begins to improve.

Headache After a Head Injury

Headache is common after a concussion, but certain symptoms require immediate evaluation.

Seek emergency care after a head injury if there is:

• Repeated vomiting

• Increasing confusion

• Severe or worsening headache

• Seizure

• Weakness or numbness

• Difficulty waking

• Slurred speech

• Significant behavior change

• Loss of consciousness or other concerning neurologic symptoms

People taking anticoagulant medications may require additional caution after head trauma.

When Does a Headache Need Imaging?

Not every headache requires a CT scan or MRI.

Imaging may be considered when there are concerning features such as:

• Sudden severe onset

• Abnormal neurologic examination

• Significant trauma

• New seizure

• Certain new or changing headache patterns

• Concern for another underlying medical condition

For patients with a typical history of recurrent migraine and a normal neurologic examination, routine imaging is often unnecessary.

Your healthcare provider can determine whether imaging or specialist evaluation is appropriate.

How Emcura Can Help

At Emcura Medical Clinic, we take a comprehensive approach to headache evaluation.

Depending on your symptoms, we may assess:

• Headache pattern and duration

• Neurologic symptoms

• Blood pressure

• Hydration

• Sleep

• Stress

• Hormonal changes

• Medication use

• Respiratory or sinus symptoms

• Migraine triggers

• Previous headache history

Treatment may include:

• Acute symptom relief

• Migraine-specific medications when appropriate

• Anti-nausea treatment

• Hydration recommendations

• Lifestyle and trigger management

• Preventive treatment discussions

• Referral for imaging, neurology, or emergency evaluation when indicated

Our goal is to help patients achieve fewer headaches, better symptom control, and a clear understanding of when a headache needs more urgent attention.

The Bottom Line

Most headaches are not dangerous, but recognizing the pattern matters.

A typical tension headache often causes mild to moderate pressure or tightness, while migraine commonly causes more significant pain accompanied by nausea, light or sound sensitivity, and worsening with activity.

New, persistent, increasingly frequent, or changing headaches deserve medical evaluation.

A sudden severe headache, new neurologic symptoms, confusion, seizure, significant vision loss, fever with neck stiffness, or severe headache after significant trauma requires emergency medical attention.

At Emcura Medical Clinic, our providers can help determine whether your symptoms are consistent with migraine or another type of headache and develop an individualized treatment and prevention plan.
