Does 13 migraine days a month mean I have chronic migraine?

No. Fewer than 15 headache days a month is described as episodic migraine. Chronic migraine is defined as 15 or more headache days a month over more than three months. Either way, a diagnosis is for a clinician — a record simply shows the pattern.

Why track migraine days rather than just remembering them?

Because frequency is hard to recall accurately, and it's the thing clinicians reason about. A dated count over several months shows whether your migraine days are steady, rising or easing — and lets you record acute-medication days alongside them, which is useful context.

What 13 migraine days a month can mean

Having 13 migraine days in a month works out to roughly 156 migraine days across a year. That is at the upper end of the episodic range — episodic migraine means fewer than 15 headache days a month, so 10 to 14 days sits just below the threshold clinicians use for chronic migraine. Many people describe this range as the point where migraine starts to shape daily life.

Where 13 days a month sits

Migraine frequency is usually described as headache or migraine days per month. Episodic migraine means fewer than 15 headache days a month; chronic migraine is defined by 15 or more. At 13 days a month — about 156 a year — you're within the episodic range. The number itself matters less than whether it's steady, rising or falling, which is exactly what a month-by-month count shows.

What this frequency means in practice

Because this is close to the chronic-migraine threshold, an accurate count really matters — the difference between 'about a dozen' and 'fifteen or more' is meaningful to a clinician. It's also worth recording how many days you use acute medication, since frequent use is associated with medication-overuse headache (commonly cited around 10 days a month for triptans and combination painkillers, 15 for simple painkillers). None of this is a diagnosis; it's context worth having.

Talking to a clinician about it

Walking into an appointment with a dated month-by-month count — migraine days, symptom severity, and acute-medication days — gives a clinician the frequency picture they need, instead of a number reconstructed from memory.

Temple counts your migraine days month by month — 13 days or 156 a year becomes a clear, dated pattern you can bring to your next appointment, not a number reconstructed from memory.
