How to Keep a Headache Journal for Your Doctor
The single most useful thing you can bring to a headache appointment isn't a list of questions — it's a record. A well-kept headache journal turns "I get a lot of headaches, I think maybe a few times a week?" into something your doctor can actually work with: how often attacks happen, how long they last, what they feel like, what you've taken, and what tends to set them off. That difference often decides whether you leave with a real plan or a shrug.
This guide covers exactly what to log, how to keep it consistent enough to be useful, and how to turn weeks of entries into a one-page summary your clinician can read in thirty seconds.
Why a headache journal matters
Headaches are invisible and forgettable. By the time you're in the exam room feeling fine, the details of last Tuesday's attack have evaporated. Memory also distorts frequency — people routinely under- or over-estimate how often they get headaches, and both errors lead to the wrong treatment decisions. A headache diary for your doctor fixes this by capturing the facts while they're fresh.
There's a clinical reason too. Diagnosing migraine versus tension-type versus other headache disorders depends heavily on pattern: timing, triggers, associated symptoms, and response to medication. A good migraine log is often what separates a confident diagnosis from months of guessing. And if you're starting a preventive medication, a baseline record is the only way to honestly tell whether it's helping.
What to record for every attack
You don't need to write an essay. For each headache, capture a consistent set of fields:
- Date and start time. When it began, as precisely as you can.
- Duration. When it ended, or roughly how many hours it lasted.
- Severity. A simple 1–10 scale is fine, as long as you use it the same way each time.
- Location and quality. One side or both, front or back; throbbing, pressing, stabbing.
- Associated symptoms. Nausea, vomiting, light or sound sensitivity, aura, dizziness, neck pain.
- Medication taken. What you took, the dose, the time, and whether it worked.
- Likely triggers. Sleep, food, stress, hormones, screens, alcohol, and weather.
Consistency matters more than completeness. Five fields filled in every single time are far more useful than fifteen fields filled in occasionally.
Track the triggers that hide in plain sight
The trigger column is where journals earn their keep, because the real culprits are often the ones you'd never connect by memory alone. Sleep is the classic example — both too little and a weekend lie-in can provoke an attack a day later. Skipped meals, dehydration, and caffeine timing matter too.
Weather is the most under-recorded trigger of all. Many weather-sensitive people are reacting to barometric pressure swings rather than temperature or rain, and pressure is invisible — you can't feel it the way you feel humidity. Logging the pressure trend alongside your attacks is the only practical way to see whether a drop the day before a storm reliably lines up with your headaches. If it does, that's a pattern worth showing your doctor and planning around.
Keep it consistent — the habit is the hard part
The best journal is the one you actually keep. A few things make that easier:
- Log in the moment, not at the end of the week. Recall decays fast.
- Lower the friction. A notebook by the bed or an app on your phone beats a perfect system you never open.
- Note the misses too. "No headache, slept well, pressure steady" days are data — they're what your headache days get compared against.
- Don't judge your entries. This is a record, not a report card. Skipped a day? Just start again.
If pen and paper works for you, keep it simple and structured. If you'd rather have your triggers — especially weather — captured automatically, an app removes most of the effort.
Turn weeks of entries into a one-page summary
Walking in with sixty raw entries is almost as unhelpful as walking in with nothing, because your doctor has fifteen minutes. Before the appointment, distill your log into a short summary:
- Frequency: headache days per month, and how many were severe.
- Pattern: time of day, day of week, or cycle timing if relevant.
- Top triggers: the two or three that show up most often.
- Medication response: what you've tried, and whether it reliably works.
- Trend: getting better, worse, or holding steady.
That one page lets your clinician spend the visit on decisions instead of data entry. Bring the full log as backup in case they want to dig into specifics.
How Pressure Pal helps
Pressure Pal is built for the part of this that's hardest to do by hand: tying your attacks to the barometric pressure trend. You log an episode with its severity and symptoms, and it sits right next to the local pressure curve, so the weather connection either shows up clearly or it doesn't. Over a few weeks you get exactly the kind of summary — frequency, triggers, and the pressure pattern — that's easy to hand to a doctor, without having to reconstruct it from memory the night before your appointment.
Bottom line
A headache journal is the highest-leverage thing you can do between appointments. Record a consistent handful of fields for every attack — timing, severity, symptoms, medication, and triggers including weather — keep it up reliably, and condense it into a one-page summary before you go in. Do that, and you give your doctor what they need to actually diagnose and treat you, instead of guessing from a hazy story.
