How long does physiotherapy take to work for muscle strain?

A strain involves overstretched or damaged muscle fibres. The affected muscle, severity, pain, strength loss and the demands of your job or sport all influence progress. Treatment commonly starts with comfortable movement and gradually introduces resistance. A temporary improvement in pain does not necessarily mean the tissue is ready for sprinting, lifting or sudden changes of direction.

Use the home programme consistently, but keep each exercise within the agreed level. Warm up as advised, avoid sudden increases in load and record how the muscle responds later that day and the next morning. Tell your therapist about repeated flare-ups, weakness or difficulty with a specific task. Learn more about [Muscle Strain](/conditions/muscle-strain/) and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Seek assessment if you felt a pop followed by marked weakness, cannot use the limb normally, develop substantial swelling or bruising, or have pain that is worsening. Reassessment is appropriate when progress stops or the muscle repeatedly gives way during ordinary activity.

Ask what level of stretching and resistance is appropriate, which movement should be tested before return to sport, and how to increase activity without overloading the healing muscle. Clarify what to do after a painful flare.
