Educational tools only — not medical care
Migraine Trail is not a healthcare provider, medical service, or medical device. These tools use information you enter and simplified educational rules. They may be incomplete or wrong and cannot examine you.
- Results do not diagnose, rule out, confirm, or predict any disease, headache type, trigger, emergency, or personal medical risk.
- Do not start, stop, combine, delay, or change a medicine or treatment—and do not delay professional care—because of a result.
- Labels such as “pattern,” “alignment,” “score,” “threshold,” “risk,” or “urgency” are educational summaries, not clinical findings or probabilities.
Discuss symptoms and decisions with a licensed healthcare professional who knows your history. For a child, involve a parent or guardian and an appropriate pediatric clinician.
If symptoms may be an emergency, stop using this site. Call your local emergency number or seek emergency care now. Never wait for or rely on a tool result.

Medication-Use Day Counter
Count the days you used acute headache medicine and compare your entries with medication-overuse headache screening thresholds.
Count days, not doses. If you took the same medicine twice on Tuesday, that is one use day. Count each medicine class used that day, but count Tuesday only once in your total acute medication days.
What these thresholds mean
ICHD-3 criteria use 10 days/month for triptans, opioids, and combination analgesics, and 15 days/month for simple non-opioid pain relievers, when the pattern continues for more than three months. Use across multiple classes can also matter.
Medication-overuse headache also involves headache on 15 or more days/month in a person with an existing headache disorder. This counter cannot evaluate every diagnostic detail, classify every medicine, or replace a clinician’s assessment.
Frequently asked questions
What counts as a medication-use day?
Count a calendar day once for each class used, regardless of the number of doses. For the total, count the day only once even if you used multiple classes.
Can this diagnose medication-overuse headache?
No. It is an educational screening aid. A clinician must review your full headache history, diagnoses, medicines, and other possible causes.
Should preventive medicine be included?
No. Enter medicines used to treat an attack or headache as it happens. Ask a clinician or pharmacist if you are unsure whether a medicine is acute or preventive.
