What is the first treatment for muscle strain?

A muscle strain happens when muscle fibres or their tendon attachment are overstretched or injured. It may cause a sudden ache, tightness, tenderness, weakness, or bruising. The first phase of care reduces loading without keeping the body completely still. Read more about [Muscle Strain](/conditions/muscle-strain/).

Pause running, lifting, or any movement that reproduces the pain. Keep the area supported and use a cold pack wrapped in a towel for short applications. Light compression can be useful when comfortable, but loosen it if the skin becomes pale, numb, or tingly. Do not test the injury with vigorous stretching, sprinting, or deep massage. When pain settles, gentle range-of-motion work and progressive strengthening can help restore normal use. A physiotherapist can match exercises to the injured muscle. Explore [Hot and Cold Therapy](/treatments/physiotherapy-and-rehabilitation/hot-and-cold-therapy/) and [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Seek prompt care for a popping sensation followed by marked weakness, a visible gap or deformity, rapidly increasing swelling, or extensive bruising. Medical review is also sensible when walking or using the limb is very difficult, pain keeps increasing, or symptoms do not begin to settle with sensible activity modification. Urgent assessment is needed for numbness, a cold limb, or severe pain after significant trauma.

Ask which movements are safe now, whether the injury needs imaging, and how to judge readiness for work or sport. Ask when hands-on treatment may be suitable; [Sports Massage](/treatments/manual-and-manipulative-therapy/sports-massage/) is generally considered only after the acute tenderness has eased.
