A new ache, stiffness or change in movement is worth noticing, but it does not automatically mean tissue damage or predict a future injury. A short record can help you describe what has changed and make a more useful next decision. It cannot diagnose the cause.

Keep a short, useful record

For a week or two, jot down only details that help you understand the pattern or explain it to a health professional: what you were doing and for roughly how long; where you felt symptoms; whether they changed your movement or daily tasks; and how they changed during the activity, later that day and the next day. Sleep or a sudden increase in workload may also be relevant.

Use simple descriptions such as mild, moderate or severe if a number scale feels unhelpful. Look across several days rather than treating one difficult day as proof that an activity is harmful. You do not need to track every sensation.

Use the notes to adjust, not self-diagnose

If an activity repeatedly leads to a substantial or lasting increase in symptoms, consider reducing its duration or intensity and discuss the pattern with a suitable clinician. If it feels manageable and symptoms settle, you may be able to continue or build gradually. Avoid using a pain score on its own as a stop-or-go rule; its meaning depends on the condition, the person and the wider pattern.

When to seek help

Seek assessment if pain is new and severe, keeps worsening, limits normal activities or does not improve with sensible adjustments. For urgent injury signs and NHS advice, read when to pause training and seek help after a sports injury and the NHS guidance on sprains and strains.

Bring the pattern into a conversation

A short record can help you explain what you have noticed and what you want to do more comfortably. It cannot prove what caused the symptoms. For persistent pain, NICE recommends person-centred assessment and shared care planning, including reassessment when symptoms change.
