Why this exists
You remember the pain. You forget the pattern.
By the time you're sitting across from a neurologist, the details have blurred — which side, how many days this month, whether it was the wine or the weather or the week before your period. So you guess. And the guess is usually an undercount.
That gap is where good treatment stalls. Migraine care runs on frequency, triggers, and response to medication — three things that are almost impossible to reconstruct from memory alone, three months after the fact.
A number worth knowing
Using acute pain relief on 10–15+ days a month can, on its own, start making headaches worse — a cycle called Medication Overuse Headache. Most people cross that line without ever counting the days. The tracker counts them for you.
