Asked constantly. Answered honestly.
Short, direct answers to the questions migraine people actually type into a search box — with the evidence where it exists, and honesty where it doesn't.
How long do migraines last? The 4–72 hour rule, the four phases, and when an unusually long attack needs medical care. Can weather really cause migraines? For a subgroup, yes — what the evidence shows and how to test yourself. Why keep a migraine diary? What the evidence shows about diaries, diagnosis, and treatment decisions. What's the best way to track triggers? Immediacy, context and volume — and why single-trigger hunting misleads. App vs paper diary: which works better? Paper's real virtues, where it fails, and the screen-during-attack problem. How to prepare for a neurologist appointment What to bring, what you'll be asked, and how a diary report changes the visit. How to export your migraine history as a PDF Why doctors prefer summaries over app screens, and what a good export contains. Are migraine tracking apps private? The red flags to check in any health app — accounts, ads, analytics, data sharing. Is there a migraine app without an account? Why most health apps demand signup, and what no-account design means for privacy.
