A new ache, stiffness or change in movement is worth noticing, but it does not automatically mean tissue damage or predict a future injury. Look at the whole picture: how the symptom began, what changes it, whether it is settling and whether it is limiting an activity that matters to you.

Pause and adjust

If an activity sharply increases symptoms or changes how you move, stop that version of the activity and reduce or modify the demand. Avoid repeatedly testing the sore area or forcing a stretch. If the discomfort is mild and settling, try a comfortable level of ordinary movement and see how you respond.

Notice useful changes

Pay attention to whether symptoms are improving or worsening, whether swelling or bruising appears, and whether your strength, movement or everyday function changes. These observations cannot diagnose an injury, but they can help you decide whether to modify activity or seek an assessment.

When to seek help

Seek urgent advice for very painful or worsening symptoms, substantial or increasing swelling, difficulty bearing weight, or symptoms that are not improving. After an injury, call 999 or go to A&E if the area is deformed, numb or tingling, blue or grey, cold, or you heard a crack. Check the NHS sprains and strains guidance for full advice. For sports injury-specific guidance, see when to pause training and seek help.

Make a manageable next step

Depending on the situation, a next step might be a lighter training session, a walk, a planned break or getting advice from an appropriately qualified clinician. If symptoms keep returning or affect daily life, arrange an assessment rather than relying on repeated self-treatment. Read the NHS overview of ways to manage pain or our guide to persistent pain.
