How Do I Know If I Have Chronic Migraine?

Key Points

• Chronic migraine is diagnosed when you have headaches 15 or more days per month, with at least 8 days having migraine features, for three months or longer 
• Chronic migraine differs from episodic migraine in frequency, not just severity 
• Common warning signs include increasing migraine frequency, medication overuse, and significant life impact 
• Effective treatments including Botox injections and CGRP inhibitors can significantly reduce migraine frequency 
• Early intervention with a neurologist can prevent episodic migraines from becoming chronic 

You've been getting migraines for years. Maybe they started as an occasional thing: once a month, always around your period, or triggered by specific foods or stress. Annoying, but manageable. 

But lately, something's changed. The headaches are happening more often. You're calling in sick to work more frequently. You've started keeping track, and you realize with growing concern that you're dealing with migraine symptoms more days than not. 

So you start wondering: is this still just "migraines," or has it become something else? Something chronic? 

At Neurological Specialties, we hear this question all the time. Let's walk through exactly how to know if you have chronic migraine, what that diagnosis means, and what can be done about it. 

What Defines Chronic Migraine? 

Chronic migraine isn't just "really bad migraines" or "migraines that happen a lot." It's a specific medical diagnosis with clear criteria established by the International Headache Society. 

Here's the official definition: You have chronic migraine if you experience headaches on 15 or more days per month, with at least 8 of those days having migraine features, for three months or longer. 

Let's break that down: 

15 or more headache days per month - This is the frequency threshold. You're dealing with a headache, even if mild, more than half the days of the month, consistently. 

At least 8 days with migraine features - Not every headache day has to be a full-blown migraine, but at least 8 days per month need to have typical migraine characteristics like throbbing pain, nausea, or light sensitivity. 

For three months or longer - One really bad month doesn't count. This pattern needs to persist for at least three consecutive months. 

If you meet these criteria, you have chronic migraine. It's not a judgment on how well you're handling things. It's a legitimate neurological condition that requires proper treatment. 

The Difference Between Episodic and Chronic Migraine 

The main difference is frequency, not severity. 

Episodic Migraine means fewer than 15 headache days per month. You might have a few migraines per month with headache-free days in between, or attacks that follow predictable patterns. 

Chronic Migraine means headaches become almost constant. You might have some days with severe, classic migraine attacks, some days with milder headaches that still have migraine features, and very few completely headache-free days. 

Think of it this way: episodic migraine is like severe weather that rolls through occasionally. Chronic migraine is like living in a climate where bad weather is the norm, with occasional severe storms making things even worse. 

The transformation from episodic to chronic migraine often happens gradually, which is why people don't always realize when they've crossed that threshold. 

Warning Signs Your Migraines Are Becoming Chronic

Watch for these red flags: 

Increasing Frequency - If you used to get migraines a few times a month and now you're having them multiple times per week, track your headache days. If you're approaching or exceeding 15 headache days per month for several months in a row, you're meeting the criteria for chronic migraine. 

Medication Overuse - Taking acute migraine medications (triptans, pain relievers, combination drugs) more than 2-3 times per week can create a vicious cycle. Medication overuse headache is one of the most common reasons episodic migraines become chronic. 

Baseline Daily Headache - You wake up every morning with some level of head pain. Some days it's mild, other days it explodes into a full attack. You can't remember the last completely headache-free day. 

Increasing Life Impact - You're missing work regularly, canceling plans, avoiding activities you used to enjoy. Your life is shrinking around your headaches. 

Loss of Treatment Response - Medications that used to work aren't helping as much anymore. 

If any of these sound familiar, it's time to see a specialist. Dr. Henkel at Neurological Specialties specializes in diagnosing and treating chronic migraine. Early intervention can sometimes prevent full transformation to chronic migraine or get you started on effective treatment sooner. Call (813) 876-6321 to schedule an evaluation. 

Common Symptoms of Chronic Migraine

During migraine attacks, you might experience:

Headache characteristics: 

• Moderate to severe throbbing or pounding pain 
• Often on one side of the head 
• Worsens with physical activity 
• Lasts 4-72 hours if untreated 

Associated symptoms: 

• Nausea and vomiting 
• Light sensitivity (photophobia) 
• Sound sensitivity (phonophobia) 
• Smell sensitivity (osmophobia) 

Migraine aura (some people): 

• Visual disturbances (zigzag lines, blind spots, flashing lights) 
• Sensory changes (numbness, tingling) 
• Speech or language difficulties 

Between attacks: 

• Low-grade headache or head pressure 
• Neck pain and stiffness 
• Fatigue and brain fog 
• Mild light or sound sensitivity 

With chronic migraine, you're dealing with symptoms more days than not, which takes a serious toll on quality of life. 

What Causes Chronic Migraine? 

Several factors contribute to the transformation from episodic to chronic migraine: 

Ineffective Treatment of Migraine Attacks 

Getting insufficient relief from treatments for episodic migraine can lead to central sensitization, which can lower the threshold of migraine and promote chronification. This is why proper treatment of episodic migraine is so important.

Medication Overuse 

Taking acute headache medications too frequently can actually increase migraine frequency: 

• Triptans more than 10 days per month 
• Over-the-counter pain relievers more than 15 days per month 
• Combination medications frequently 

Breaking the medication overuse cycle is often essential for improvement. 

Other Contributing Factors 

• Chronic stress, anxiety, and depression 
• Obesity 
• Sleep disorders (sleep apnea, insomnia, irregular sleep) 
• Physical trauma (concussion, whiplash) or significant life stressors 
• Hormonal fluctuations (for women) 

Understanding these factors is important because addressing them is part of an effective treatment plan.

How We Diagnose Chronic Migraine

When you come to Neurological Specialties for evaluation, Dr. Henkel will conduct a thorough assessment.

Headache History and Diary 

The most important diagnostic tool is a detailed headache history. We'll ask about: 

• How many headache days per month 
• Headache characteristics (location, quality, intensity, duration) 
• Associated symptoms 
• Triggers 
• Medications and frequency of use 
• Impact on daily life 

Keeping a headache diary for at least a month before your appointment is incredibly helpful. Track every headache day, pain intensity, symptoms, medications taken, and potential triggers. 

Make sure to review what to bring to your appointment so you're fully prepared. 

Physical and Neurological Examination 

Dr. Henkel will perform a thorough neurological exam to rule out other causes and identify contributing factors. This exam is typically normal in people with chronic migraine, which is reassuring because it means there's no structural problem. 

Diagnostic Testing (When Needed) 

For most people with typical chronic migraine, extensive testing isn't necessary. However, imaging or tests might be recommended if:

• Your headache pattern has changed significantly or suddenly 
• You have unusual neurological symptoms 
• You're not responding to appropriate treatment 

Tests might include MRI or CT scans, blood tests, or EEG testing.

Treatment Options for Chronic Migraine 

Here's the good news: chronic migraine is highly treatable. Most people see significant improvement with proper treatment. 

Preventive Medications 

Botox (OnabotulinumtoxinA) - Botox injections are FDA-approved specifically for chronic migraine. Injections are given every 12 weeks in specific head and neck locations. Many patients experience significant reduction in headache days. We offer in-office treatments including Botox for chronic migraine. 

CGRP Inhibitors - These newer medications specifically block CGRP (calcitonin gene-related peptide), a molecule involved in migraine attacks. Options include monthly injections or quarterly infusions. Many patients see dramatic improvement. 

Finding the right preventive medication often takes trial and error and 2-3 months to show full benefit. 

Acute (Rescue) Medications 

Even with good preventive treatment, breakthrough migraines happen: 

Triptans - Medications like sumatriptan, rizatriptan, or eletriptan work by preventing CGRP release from nerves. Most effective when taken early. 

Gepants - Newer acute migraine medications (ubrogepant, rimegepant) that block CGRP from binding to nerves and blood vessels. Some can be used for both acute treatment and prevention. 

NSAIDs - Anti-inflammatory medications can help if taken early, though use carefully to avoid medication overuse. 

Anti-nausea medications - Treat nausea and can sometimes help with the headache itself. 

The key is using acute medications strategically (not more than 2-3 days per week) to avoid medication overuse headache. 

Breaking the Medication Overuse Cycle 

If medication overuse is contributing to your chronic migraine, treatment involves: 

• Stopping or reducing the overused medication 
• Starting preventive treatment 
• Managing withdrawal symptoms 
• Developing a safe plan for limited acute medication use 

This process can be challenging but is often essential for improvement. 

Lifestyle Modifications 

While not a substitute for medical treatment, lifestyle changes support migraine management: 

• Consistent sleep schedule (7-8 hours, same time daily) 
• Regular meals (don't skip) 
• Stay hydrated 
• Regular moderate exercise 
• Stress management (meditation, yoga, therapy) 
• Trigger avoidance 
• Limit caffeine (keep consistent and moderate)
