In short: a symptom timeline is a one-page list, in order, of when a symptom started and how it changed since: each change on its own line, with how strong it was, what you tried and what happened after. This free template lets you fill it in on this page, print it or save it as PDF for your appointment. What you type stays in your browser; nothing is sent anywhere.
| What it records | First noticed, every change in order, intensity 1–10, what you tried, what happened after |
|---|---|
| How long it takes | About 5 minutes the first time, a few seconds for each new change |
| What you take to the visit | One printed page or a PDF, oldest change first |
| Cost | Free, no sign-up |
In order, on one page
A short summary at the top (main symptom, first noticed, better or worse overall, your question), then one line per change.

How do I make a symptom timeline for my doctor?
Start with the day you first noticed the symptom, then add one line for every change, oldest first.
- Write the main symptom and the date you first noticed it, even if it is approximate ("early March").
- Add a line each time something changed: it got stronger, moved, came at a new time of day, stopped or came back.
- Give each line an intensity from 1 to 10, so the doctor sees the trend at a glance.
- Note what you tried (rest, a medicine, a change in diet) and what happened after.
- At the top, write whether it is better, the same or worse overall, and the one question you most want answered.
- Press Print or save as PDF before the appointment.
Why does a doctor want a symptom timeline?
Because the order of events is part of the story, and memory is unreliable after a few weeks.
The American Medical Association publishes a symptom and medical history timeline form for the same reason: when a symptom began, how it changed and how it responded to treatment helps a clinician understand what is going on. Mayo Clinic's advice for a productive visit also suggests writing down when a symptom first appeared, which medicines you took and how your body responded. A timeline you wrote at the time is more precise than one reconstructed in the waiting room.
What should a symptom timeline include?
When, what changed, how strong, what you tried and what happened after; everything else is optional.
- When: a date, or "two days after the flu shot" if that is how you remember it.
- What started or changed: in your own words ("headache behind the eyes, every afternoon").
- Intensity 1–10: the same scale every time.
- What you tried: medicines with the dose, rest, heat, a change in food or sleep.
- What happened after: better, no change, worse, how long it lasted.
- Optional: triggers you noticed, sleep, travel, other people ill around you.
Example of a symptom timeline
| When | What started or changed | 1–10 | What you tried | What happened after |
|---|---|---|---|---|
| 3 March | Headache behind the eyes in the afternoon | 4 | Water, short walk | Gone by evening |
| 10 March | Same headache, now most days | 5 | Paracetamol 500 mg | Better after an hour |
| 18 March | Headache with blurred vision in the evening | 6 | Less screen time | No change |
| 25 March | Wakes me up at night twice this week | 7 | Booked an appointment | — |
The example shows the format only; it is not advice about any symptom. If a symptom is sudden and severe, call your local emergency number (112 in the EU) instead of keeping a timeline.
Timeline or symptom diary?
A timeline tells the story of one problem in a few lines; a diary records every day.
Use the timeline when you have one main complaint and an appointment coming up. Use the symptom diary template when you need daily detail over weeks, for example to see what comes before a flare. Many people keep a diary and write the timeline from it before the visit.

Frequently asked questions
What is a symptom timeline?
A list, in order, of when a symptom started and every change since, with intensity, what you tried and what happened after. It fits on one page so a doctor can read it quickly.
How do I write a symptom timeline for a doctor?
Start with the date you first noticed it, add one line per change, oldest first, rate each line from 1 to 10 and note what you tried. Put a two-line summary and your main question at the top.
Is there a free symptom timeline template?
Yes, this page: fill it in online, print it or save it as PDF, without signing up. What you type stays in your browser.
How far back should a symptom timeline go?
To the first time you noticed the symptom, even if it was months ago. Approximate dates are fine; the order matters more than the exact day.
Can I keep the timeline on my phone?
Yes. Save it to Anpheros Daily, free, to keep adding changes and show it during the visit. The app does not diagnose; it keeps your notes in order.
Does a timeline replace seeing a doctor?
No. It helps you explain what happened. Decisions about what the symptom means belong to your doctor.
