Most people describe a headache in a sentence or two, such as "I've had headaches lately." That is a fair summary, but it leaves out the details that help someone understand what is going on. A short written record, kept for a few weeks before you book an exam, can make the next conversation more useful for both you and the person listening.
Start With a Simple Calendar
Take a sheet of paper or a note on your phone and write the date of each headache you remember over the past month. Next to each date, add the time it started, how long it lasted and where you felt it, such as the forehead, one side of the head, the back of the neck or behind the eyes. Patterns often show up faster on paper than they do in memory, especially when headaches come and go without warning.
Be specific about what you noticed. "Tuesday afternoon, about two hours, worse when I was looking at the screen" is more useful than "bad all week." If you are not sure of a detail, write that down too. An honest "I don't know" is more helpful than a guess presented as fact.
Notes on What Happened Around Each Headache
For each entry, look back at the previous day or two. Did you skip a meal, sleep fewer hours than usual, or spend a long stretch at a desk or in a car? Did you drink less water than normal, have a stressful day, or change a routine such as caffeine, alcohol or a new medication? Did the weather shift, or were you in a room with bright light or strong smells? You are not trying to prove a cause. You are collecting observations so a professional can ask better questions.
It also helps to note what you did about the headache and what happened next. Write down whether you lay down, took an over-the-counter product, applied a cold or warm cloth, or simply waited. Record the result in plain words, such as "better after an hour" or "no change." If you take any product for headaches, bring the name and the amount you used, since a list of what you took can matter as much as the headache itself.
Changes That Call for Urgent Care
Most headaches are not emergencies, but some signs mean you should not wait for an appointment. Seek emergency care right away if a headache is sudden and severe, feels like the worst you have ever had, or arrives with confusion, trouble speaking, weakness or numbness on one side of the body, loss of vision, a stiff neck with fever, fainting, or a headache that follows a head injury. Do not try to fit these signs into a calendar entry. Call emergency services or go to the nearest emergency department.
Even when a headache is not an emergency, note any change in its pattern. A headache that becomes more frequent, wakes you from sleep, or behaves differently from your usual headaches deserves a prompt call to a clinic. Write down the date the change began so you can share it clearly.
Bringing Your Notes to the Visit
Print your calendar or keep it open on your phone. Before the appointment, read the entries aloud to yourself and circle anything that surprised you. Put the most important points at the top, such as how often headaches occur, how long they last and whether anything seems to make them better or worse. Mention any recent head injury, illness, travel, or change in sleep or work schedule, even if it feels unrelated.
A clinic team can only work with what you bring them. They will ask questions, perform an exam where appropriate and decide what, if anything, comes next. Your job is to arrive with a clear, dated account, not a diagnosis. Avoid searching online for a label to match your symptoms, since that often adds worry without adding clarity.
Keep the Record Going
A good headache record is not a one-time project. Continue the calendar for a few weeks, even after you book, and bring it to follow-up visits. A steady record can show whether things are improving, staying the same or changing, and it gives you a habit of noticing your body without fear. Keeping notes is one of the most practical steps you can take this week, and it costs nothing but a few minutes each day.
