How to use the monthly headache day tally
The most useful thing you can bring to a headache appointment is dates, not impressions. This tally takes the number of days in the month, the days you had a headache and how many of those days you took a pain reliever, then reports both counts, each as a share of the month, the medication share of your headache days, and the headache days you got through without medication.
The arithmetic is division only: headache days divided by days in the month, times 100, and the same for medication days. Shares are shown to one decimal place. If headache days exceed the days in the month, or medication days exceed headache days, the inputs contradict each other and the page says so instead of calculating.
This page assigns no headache type and produces no score or grade. Sorting headaches into types is clinical work, and no day count at which preventive treatment begins is offered here, because that figure is not confirmed in an authoritative source. Current as of October 2026, and not a medical diagnosis. A headache that starts suddenly and severely, one that arrives with neurological signs, or one that has changed from your usual pattern needs care without delay.
Frequently Asked Questions
Headache types are sorted out by a clinician who weighs the pattern and the accompanying symptoms together. Calling a type from a few input boxes would delay care whenever it is wrong. This page tallies dates instead, in the form you can hand straight to a clinician.
Count the days on which you took something, not the number of tablets. This tally asks only about doses taken on headache days, so leave out medication you took on headache-free days for another reason.
That figure is not offered here. Take the counts and shares to an appointment and discuss them. If your headache days or your medication days are climbing, that change is itself important information for a clinician.
