The full SNNOOP10 checklist that specialists use — thunderclap onset, positional pain, papilloedema symptoms and the rest. Nothing is skipped because a question seemed unlikely.
Your answers are checked against the ICHD-3 diagnostic criteria, and you are told which ones you meet and which you do not — not just a label.
A headache that began on a day you can name and never stopped has a name. This tool asks about it directly, instead of filing everything under chronic migraine.
A last look before this is assessed.
A quick automated check keeps this free for everyone.
