Have you ever experienced a migraine headache? Depending on how often you experience symptoms, you may be having episodic migraines (EM) or chronic migraines (CM).
If you go weeks or months between migraine attacks, you may have EM. If you have migraine symptoms on 15 days or more per month, and within at least three months, you may have CM, advises the Mayo Clinic. Most people who experience migraine headaches never develop CM.
Your doctor may diagnose you with EM if you have:
- at least five migraine attacks in your lifetime
- headaches that affect you on less than 15 days each month
- headaches that typically last less than 24 hours
There’s no single test for migraines. To diagnose EM, your doctor will ask about your symptoms. Migraine headaches are often unilateral and described as a pulsing or throbbing sensation. The headache is often accompanied by nausea, vomiting, light sensitivity, or sound sensitivity.
Common triggers for EM include stress, menstruation, and weather changes among others. Your doctor will also take steps to rule out other possible causes. For example, you might be experiencing headaches as a side effect of medications or a symptom of an eye disorder or a brain injury.
If you’re experiencing migraine symptoms for more than 4 hours at a time and more than 15 days per month, your doctor may diagnose you with CM. People with CM have more headache days per month than people with EM. They also experience longer headaches on average.

In comparison, people with EM have headaches that last an average of 38.8 hours without treatment and 12.8 hours with treatment.

To treat EM headaches, your doctor may recommend over-the-counter medications. Depending on the frequency and severity of your symptoms, they may also prescribe prescription medications.
Your doctor may also recommend over-the-counter or prescription medications to treat symptoms of CM. They may also try to prevent CM symptoms by prescribing preventive medicines.
Certain cardiovascular drugs, antidepressants, antiseizure drugs, onabotulinumtoxinA (Botox), or pain relievers may help reduce the frequency, length, or severity of your headaches.
Most people who experience EM never develop CM. According to researchers in
Migraines are more than just painful. They can also interfere with your ability to participate in daily activities.
If you have CM, you will likely miss more work and time with your loved ones than you would with EM.
