Migraine and Headache Symptom Diary: What to Track

Migraine and headache symptoms can be hard to explain after the attack has passed. You may remember the pain, nausea, light sensitivity, or brain fog, but the details that help a clinician are often more specific: how often it happens, how long it lasts, how severe it gets, what symptoms come with it, what medication you took, what helped, what did not help, and what the episode stopped you from doing.

A migraine or headache diary does not diagnose migraine, tension-type headache, cluster headache, medication overuse headache, POTS, EDS, MCAS, Long COVID, or any other condition. It helps you bring a clearer pattern to a clinician who can evaluate it.

Start with headache days, not every possible trigger

The simplest useful headache diary starts with the event itself.

Track:

• date
• start time
• end time or total duration
• pain severity: 0 to 10, mild/moderate/severe, or your own simple scale
• pain location: one side, both sides, forehead, behind eye, neck, whole head
• pain type: throbbing, pressure, stabbing, burning, tight, pulsing
• whether it was a new pattern or your usual pattern
• whether you could function normally

Example: “Started 9:30 a.m., right temple and behind eye, throbbing 7/10, nausea and light sensitivity, lay down from 10:00 to noon, missed work call.”

That is already more useful than “bad migraine.”

Add associated symptoms

Headache disorders often involve more than head pain. Keep the connected symptoms visible.

Track whether you had:

• nausea or vomiting
• light sensitivity
• sound sensitivity
• smell sensitivity
• dizziness or lightheadedness
• visual changes
• numbness, tingling, or speech changes
• neck pain
• brain fog
• fatigue
• weakness
• tearing, stuffy nose, or eye redness
• symptoms that changed with posture

If a symptom is new, severe, unusual, or concerning, seek medical advice promptly. A diary is not a substitute for urgent care.

Track medication timing and response

Medication notes are one of the most appointment-useful parts of a headache diary.

Record:

• medication or treatment name
• dose, if you normally track it
• time taken
• how long after headache start you took it
• whether symptoms improved
• whether you needed another dose
• side effects
• whether you used prescribed, over-the-counter, or non-drug treatment
• days when you took pain medicine or migraine medicine

Do not change medications based on a diary alone. Bring the pattern to your clinician, especially if you are using acute medications often or they are not working well.

Treat possible triggers as clues, not blame

Migraine triggers can be complicated. Sometimes a “trigger” is actually an early symptom of an attack. Sometimes several factors overlap: poor sleep, stress, skipped meals, weather change, period, dehydration, bright light, alcohol, or exertion.

Use cautious wording:

• “possible trigger: poor sleep”
• “possible trigger: skipped lunch”
• “possible trigger: period day 1”
• “possible trigger: weather change”
• “possible trigger: screen-heavy morning”
• “possible trigger: dehydration”

Patterns over weeks are more useful than one memorable attack.

Include sleep, meals, hydration, and cycle context

You do not need a perfect lifestyle log, but a few context points can help.

Track:

• sleep quality
• bedtime and wake time if relevant
• skipped meals or late meals
• caffeine changes
• alcohol, if relevant
• hydration
• heat or exertion
• stress changes
• illness or infection
• menstrual cycle day, period, ovulation, or hormone medication changes if relevant
• flare state if you have chronic illness symptoms

This is especially helpful when headaches overlap with POTS, dysautonomia, EDS, fibromyalgia, Long COVID, or ME/CFS.

Track function, not just pain

Pain severity matters, but function often tells the story clinicians need.

Write down whether the headache changed your ability to:

• work or study
• drive
• cook
• shower
• use screens
• tolerate light, sound, or movement
• care for children or family
• stand or walk
• exercise
• socialize
• sleep

“Pain 5/10 but could not look at screens for 6 hours” is a different clinical story than “pain 5/10 and worked normally.”

Know what changes deserve faster care

Seek urgent medical help for sudden severe headache, new neurologic symptoms, fainting, confusion, fever with stiff neck, headache after head injury, headache with new vision loss, or any symptom your clinician has told you is urgent.

Also ask for medical advice when headaches are new, changing, more frequent, triggered by exertion or coughing, worse with posture, or associated with unexplained vomiting.

The diary can help later. Safety comes first.

What to summarize before the appointment

Before a primary care, neurology, cardiology, allergy, or chronic illness appointment, summarize:

• number of headache days per month
• number of severe days
• average duration
• worst duration
• most common associated symptoms
• medication days per month
• treatments that helped or failed
• possible repeated triggers
• relationship to sleep, meals, hydration, period, stress, or flares
• whether symptoms changed with posture
• functional impact: missed work, school, driving, screens, caregiving, or sleep
• new or changing symptoms

Helpful questions:

• “What type of headache pattern does this look like?”
• “How many headache days or medication days should prompt follow-up?”
• “Are any symptoms red flags?”
• “Could migraine, autonomic symptoms, hormones, sleep, or medication timing be connected?”
• “What should I track until the next visit?”

Where Zebra fits

Zebra helps keep headache days, migraine symptoms, medication timing, possible triggers, sleep, hydration, cycle context, flares, functional impact, and appointment questions in one timeline.

It does not diagnose migraine or headache disorders. It helps you bring a clearer, doctor-ready pattern to the clinician who can evaluate it.

Key takeaways

• Track headache frequency, duration, severity, symptoms, medication timing, possible triggers, and functional impact together.
• Keep possible triggers as clues, not proof.
• Medication response and medication frequency are important appointment details.
• A consistent diary can make headache patterns easier for a clinician to review.
