Important medical disclaimer

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.

Free baseline comparison

Migraine Trigger Stack Checker

Compare the 24–48 hours before one attack with your usual non-attack baseline. See which changes stood out and what to track next.

A comparison—not a trigger diagnosis.

Migraine usually does not have one simple, consistent cause. Some apparent triggers may be early migraine symptoms, and a single attack cannot establish a pattern.

Complete at least 6 factor comparisons. More completed rows make the snapshot more useful.

Compare each factor

Rate the factor before the attack, then rate the same factor on a typical non-attack day.

Patterns need repetition

Migraine Trail lets you record attacks and daily context over time, helping you compare repeated patterns instead of relying on one snapshot.

Why compare with a baseline?

A factor that happens before an attack may also happen frequently without an attack. Comparing both situations helps prevent an ordinary part of your routine from standing out simply because you were looking for an explanation after pain began.

Frequently asked questions

What is migraine trigger stacking?

Trigger stacking is an informal description for several changes or exposures occurring around the same time before an attack. It is not a validated score, and a stack does not prove what caused migraine.

Why compare an attack with my usual baseline?

A factor may happen frequently on days without migraine too. A baseline comparison helps separate ordinary routine from something that was genuinely different before this attack.

Can cravings or light sensitivity be mistaken for triggers?

Yes. Food cravings, fatigue, neck stiffness, mood changes, and sensitivity to light or sound can occur during prodrome before head pain and may be mistaken for causes.

How many attacks should I track?

One snapshot is only a starting point. Repeat the comparison across multiple attacks and ordinary non-attack days, then look for changes that are consistent and reproducible.
