A calf strain is a tear in the muscles at the back of the lower leg, typically on a push-off or a sudden acceleration. People often describe feeling as though they were kicked or hit in the back of the leg. It is most common in the over-forties returning to sport. One important early step is ruling out a blood clot, which can mimic it and needs urgent medical attention.

Does this sound like you?

Most people have several of these, not all of them.

Sudden sharp pain in the calf, often with the sense of being struck
Difficulty pushing off, walking normally or going up on tiptoe
Bruising tracking down towards the ankle over a few days
Tightness and cramping in the days afterwards
Swelling, redness, heat or breathlessness — which need urgent medical review

Why it happens

A sudden push-off, acceleration or jump
Returning to running or court sport after a break
Fatigue at the end of a session or game
Reduced ankle range increasing the load on the calf
Most common from the forties onwards

What we would do about it

Roughly in this order — each step waits for the one before it.

Ruling out a blood clot where the presentation is not typical
Early protected walking, with a heel raise if needed
Progressive calf loading through range
Building to single-leg heel raises and then to hopping
A graded return to running with volume before speed
Addressing ankle stiffness, which often underlies it

See a doctor first if

Your pain followed a significant injury
It is getting worse rather than settling
It comes with numbness, weakness or unexplained weight loss

This page is general information, not a diagnosis. Symptoms overlap between conditions, so the right treatment depends on an assessment.

Swelling and warmth need checking urgently

A calf that is swollen, hot or red, or comes with breathlessness, needs same-day medical review rather than physiotherapy. A straightforward strain we can start on immediately.
