After a hard week at work your neck is tight, your head aches, and by Saturday you feel as if you are coming down with something. You have suspected for a long time that stress and chronic pain are linked. The open question is how strong that link is for you, and which way it runs.
A pain diary can narrow that down. You record stress as an observation next to your pain scores, then check after a few weeks whether the scores sit higher on stressful days. You don't decide on the cause in advance. The basics are in the guide to keeping a pain diary.
The cycle in brief
The International Association for the Study of Pain (IASP) revised its definition in 2020 and describes pain as a sensory and emotional experience. Emotion is part of pain by definition. In practice, stress can change how strongly you feel pain, and pain in turn creates stress.
The cycle usually runs through four stations:
- Tension: Under pressure you brace your shoulders, jaw and back, often without noticing.
- Sleep: Worry shortens the night, and after a short night you cope with less the next day. More on this in chronic pain and sleep.
- Attention: When you are tense, you watch your body more closely and register every twinge.
- Feedback: The pain makes you worry about work, family and the months ahead. Those worries are fresh stress.
No textbook can tell you which station carries the most weight for you. Your own entries can show it over time.
Log stress as an observation
Once you have filed stress away as the cause, you will find it behind every bad day. You remember the hits and forget the hectic days when your back stayed quiet. A tag on each entry makes you record both. Four rules keep the observation clean:
- A fixed threshold. Decide once when you set "feeling stressed", for example on a deadline day, after an argument, or when you rate your tension at 6 out of 10 or higher. Then stick to that threshold.
- Record the opposite. Set "feeling relaxed" on calm days. Without the days free of stress you have nothing to compare against.
- A fixed time. Log at the same time of day, including days with little pain.
- Separate the companions. Stress rarely arrives alone. Add "slept poorly" or "had a conflict" when they apply. Otherwise you can't tell later whether stress or the short night made the difference.
Delay is a special case. Some people feel the pain a day after the stress, or on the first day off. For that pattern, create your own tag such as "stressful day yesterday" and set it on the next day's entry.
Review after four to six weeks
After a few weeks you have enough entries for a comparison. These questions help you read them:
| Question | Where to look |
|---|---|
| Are scores higher on stressful days? | Average of entries with and without "feeling stressed" |
| Does the pain arrive late? | Entries with "stressful day yesterday" against the rest |
| Is sleep the real factor? | Stressful days with and without a poor night, side by side |
| Is the tag useful for comparison? | Set almost always or almost never, it leaves no second group |
A gap of a few tenths sits within the normal noise of a 0 to 10 scale. If your scores swing between 3 and 6 anyway, you need a larger difference before you read anything into it. The article on finding your pain triggers covers false patterns in more detail.
Expect the reverse direction too. On high-pain days you feel more stressed and set the tag more readily. Higher scores on stressful days then confirm the cycle without showing where it starts. A short note such as "project deadline, pain from 3 pm" records which came first.
How PainTrack handles this
In the free version:
- "feeling stressed", "feeling relaxed", "had a conflict", "feeling anxious" and "slept poorly" are among the built-in tags. You open them in an entry with "+ Add tags".
- You create your own tags, such as "stressful day yesterday", under "More" → "Tags".
- The Weekly trend card on the Analysis page compares your average for the last seven days with the previous week and with the week four weeks ago.
- You mark a job change or a house move as an event of the kind "Changed daily routine".
With PainTrack Pro:
- Trigger analysis (the "Triggers" view of the "Insights" card) compares your intensity in entries with a tag against entries without it, over 180 days. A tag appears once 12 entries are evaluated, at least 4 with it and 4 without. Below a 0.5 point difference it shows in grey as "no clear difference".
- The before/after comparison shows whether your scores shifted after an event. Details in event markers and trigger analysis.
- If a tag feels too coarse, you can track stress as its own definition on a 0 to 10 scale and see both lines together in the History chart.
Every analysis carries a note that it shows a correlation and not a cause.
Getting help
Talk to your doctor if stress and pain have had a grip on you for weeks, if you sleep badly, or if you lose interest in things that usually matter to you. Pain clinics and pain management programmes often include psychological approaches such as cognitive behavioural therapy.
If you have thoughts of harming yourself, don't wait for an appointment. In the US you can call or text 988, the Suicide & Crisis Lifeline, at any hour. In the UK and Ireland, Samaritans answer on 116 123. In an emergency, call 911 or 999.
Frequently asked questions
Can stress make physical pain worse? Stress changes muscle tension, sleep and the attention you pay to your body, and through those it can intensify existing pain. A comparison of days with and without stress shows whether it tips the balance for you. Have new or unexplained pain checked by a doctor before you put it down to stress.
How long do I need to track stress before I see anything? Plan on four to six weeks of daily entries. You need enough entries with and without stress for the comparison to hold.
Should I record stress as a number or as yes/no? A tag with a fixed threshold is enough to start. If you want to see degrees, track stress as its own definition on a 0 to 10 scale; from the second definition on you need Pro.
