Crisis calendar / Migraine calendar / Headache diary

A daily headache diary is one of the most important tools your treatment team has to help you. An accurate headache diary serves to:

• Monitor the frequency, duration and severity of your headaches over time 
• Identify patterns that may help determine triggers and improve treatment 
• Track medication use and response 
• Maintain long term records of what has worked and what has not

Together with a headache trigger tracker, a diary can help physicians plan your treatment and manage your headaches.
