First consider when the pain started and whether it is improving. Do not assume every ache after exercise is routine muscle soreness.
When to get medical help
Get urgent help
Use local emergency care if muscle pain comes with trouble breathing or swallowing, or you cannot move part of your body.

Ask a healthcare professional
Get advice for severe unexplained pain, swelling or redness around a sore muscle, or muscle pain lasting more than three days. If you think you are injured, seek advice instead of testing the area with deeper stretches.

Use your local emergency service when emergency care is needed. These examples are not a complete symptom checklist.
1. What does delayed muscle soreness mean?
Delayed-onset muscle soreness (DOMS) begins one to three days after unfamiliar or intense exercise. Pain during the activity has a different timing. This pattern cannot diagnose the cause. Note when symptoms began and what you were doing.
2. Rest or light movement: what is the choice?
Give sore muscles time to recover and avoid intense exercise for those muscles while they are sore. Cleveland Clinic describes light movement, such as a short walk or gentle stretching, as an option. You do not have to complete another workout. Choose rest if movement does not feel suitable.
3. If you stretch, keep the range comfortable
Mayo Clinic advises warming up with 5–10 minutes of light activity before held stretches, moving smoothly without bouncing, and feeling tension rather than pain. Back off if it hurts. A sore day is not a reason to increase the hold time or force a deeper position. An injury or chronic condition may require different techniques; ask a healthcare professional about appropriate movements.

4. Do not use stretching as a soreness test
Mayo Clinic notes mixed research on stretching and that some studies found no reduction in soreness after exercise. Feeling temporarily looser does not establish that a muscle has recovered. Avoid deciding whether to repeat a hard workout solely by whether a stretch feels easier.

5. Check the next routine before starting
In Unknot on iPhone, you can preview illustrated movements and written steps, adjust targets and pause. Look at the selected body areas and movements before starting. For example, if your plan says “leg routine” after a demanding leg workout, review what that routine actually asks you to do. You can leave it for another day. Keep a short note of the activity, when soreness appeared and how it changes; a completed-session record alone cannot explain the cause.

Leave room to change the plan
Your saved routine can wait. Decide whether today calls for comfortable light activity, rest or professional advice before starting the session.
Questions before you start
Does soreness mean the workout was effective?
Soreness is not required for a productive workout. Cleveland Clinic says you can benefit from exercise without experiencing DOMS. Do not chase pain as a measure of progress.
Should I finish the stretch if it hurts?
Back off rather than waiting for the timer to end. Mayo Clinic advises tension without pain. If pain persists or you suspect an injury, ask a healthcare professional which movements are suitable.
