With fibromyalgia, the pain moves around your body, fatigue piles on top, and some nights bring no rest at all. A fibromyalgia symptom tracker that asks for ten fields every evening won't survive two weeks under those conditions. You need one you can finish in half a minute on a bad day.
Three values, a fixed time and one rule about logging good days cover that. After four weeks you can read how pain, tiredness and sleep play together for you, and you can describe your weeks to your doctor in numbers. The basics of keeping a diary are in How to keep a pain diary.
Three values instead of twenty
Many people with fibromyalgia live with fatigue, unrefreshing sleep and trouble concentrating alongside the pain. If you squeeze all of that into one daily number, you lose track of which part changed. Say your pain holds steady at 5 for a month while your fatigue climbs from 3 to 7. A combined score creeps from 4 to 6, and later you can't tell what drove it.
Split your symptoms into three values instead:
| Value | Scale | When |
|---|---|---|
| Pain | 0 to 10 | evening |
| Fatigue | 0 to 10 | evening |
| Slept well | yes or no | morning |
Log sleep in the morning, while the night is still fresh. A yes or no is enough there, because right after waking you'll struggle to justify a step between 0 and 10. The link between the two gets its own article: Chronic pain and sleep.
A fourth value earns its place only if something else limits your day more than one of the three, such as morning stiffness or brain fog. Swap it in for the weakest of the three. Every extra field costs you energy on bad days, and those are the days you need the entries most.
Fixed times for your entries
Pain that moves around tempts you to log the moment a flare starts and skip the quiet days. Your diary then looks worse than your life. With a fixed time, for example half an hour before bed, you rate each day under the same conditions.
Decide once what the evening number stands for: the average of the day or its worst moment. Both work as long as you stick with your choice. If you switch the rule after three weeks, your charts end up comparing two different things.
On foggy days a step scale with Mild, Moderate and Severe takes less weighing up than a number. Pick one scale per value and keep it, or your weeks won't line up.
Good days count too
A common question at the appointment is how many days a month you feel bad. A diary that holds only bad days can't answer it. You also lose the comparison: you see what happened before a flare, but not whether the same things happened on calm days.
A 2 in the evening is a full entry. An empty day and a good day mean different things once you look at the numbers. You can't count the empty day at all, while the good day lowers your average and serves as a comparison day.
If you forget a day, add it the next morning. If more time has passed, leave the gap. After a few days your current mood colors the memory, and a backfilled number distorts more than it adds.
Next to the numbers: tags and short notes
With each entry you tick a few circumstances. A short, fixed list does the job: slept poorly, stressed, very active, rested, weather change, period. Fixed terms are easy to count after eight weeks, free-form sentences are not.
Activity deserves a closer look. After a good day you might catch up on everything that piled up and pay for it a day or two later. You only spot that pattern if you read the days after an "active" entry as well. Turning that into a sustainable baseline is the topic of Pacing chronic pain. The method for testing circumstances against each other is in How to find your pain triggers.
Keep notes to one line: infection, new treatment, appointment, unusual strain.
How PainTrack handles this
The free version gives you one active pain definition, for example "Fibromyalgia" on the 0 to 10 scale. All three scales (0 to 10, Yes / No, Mild / Moderate / Severe) are free. You record sleep with the tags "slept poorly" and "slept well", found under "+ Add tags" in the entry. A tag of your own, such as "exhausted", goes in under More → Tags. For the location you tap several regions on the body figure, which suits pain that moves around. Under More → Reminders you set your fixed time; if you've already logged that day, the reminder stays silent. Without Pro the diary shows the last three months, and older entries stay saved.
With Pro you create as many pain definitions as you like and track fatigue and sleep as separate lines in the history chart. On a Yes / No definition the buttons read "No pain" and "Pain"; for a definition called "Restless night" you read them as no and yes. Trigger analysis (Pro) compares your values on entries with and without a given tag over 180 days. Monthly reports and the PDF doctor's report come on top.
Get new symptoms checked
Even with a diagnosis in place, see your doctor about new or different symptoms, such as fever, unintended weight loss, swollen or red joints, numbness or loss of strength. Look up in your diary when the new symptom started and how often it shows up, and bring both.
Frequently asked questions
How do I track fibromyalgia symptoms? Log pain and fatigue once a day at the same time, plus whether your sleep was restful each morning. Tick a few fixed circumstances and record a value on good days as well.
What symptoms should I track for fibromyalgia? Pain, fatigue and sleep form the core. Add a fourth value such as morning stiffness or brain fog only if it limits your day more than one of the three.
How long should I keep a fibromyalgia diary? Plan on at least four weeks in a row so weekly rhythms and delayed effects show up. Before a change in treatment, start a few weeks earlier so you have a baseline.
Is there a free fibromyalgia tracker app? In PainTrack, one active pain definition, all three scales, tags, notes and reminders are free. Separate lines for fatigue and sleep, trigger analysis and the PDF report are part of Pro.
