How to Keep a Headache Diary: The Single Most Useful Thing You Can Do Before Your Appointment

You have a neurology appointment for your headaches — and you want to make the most of it. The single most useful thing you can bring is a headache diary. Here is exactly what to record and why it changes everything.

Why a Headache Diary Matters

Memory is unreliable for recurring pain. Patients often underestimate or overestimate how frequent their headaches are. A diary captures the actual pattern — which is essential for diagnosis (migraine vs tension vs cluster), measuring treatment response, and identifying triggers.

What to Record Each Day

• Date
• Did you have a headache? Yes / No (record even the headache-free days)
• Start time and end time
• Severity on a 1–10 scale
• Location: One side / both sides / behind the eyes / top of head
• Character: Throbbing / pressing / stabbing / burning
• Associated symptoms: Nausea, vomiting, light sensitivity, sound sensitivity, vision changes
• What you did: Medication taken (name, dose, time), rested, applied ice/heat
• Response to medication: Did it help? Completely / partially / not at all
• Possible triggers: Poor sleep, missed meal, stress, menstruation, alcohol, weather change, screen time

Easiest Way to Do This

A simple paper calendar works — one line per day. Free apps like "Migraine Buddy" or "N1-Headache" are specifically designed for headache tracking and generate summary reports you can show your neurologist.

What the Diary Will Show

• How many headache days per month — this determines whether preventive treatment is needed
• Patterns (e.g. always around menstruation, always on weekends — the "let-down" migraine)
• Whether medication is being overused (more than 10–15 days/month)
• What triggers to avoid

"Bring me 4 weeks of headache diary data and I can tell you more in 15 minutes than from any scan or blood test. The diary is the single most powerful diagnostic tool for headache disorders."
