Calf Strain
Calf strain ranges from the tearing of a few muscles fibres to completely rupturing the muscles itself causing a person pain in the calf area.

What causes calf strain?
The calf muscle is usually strained whilst running or walking as the calf muscle's function is to control the heel bone and they are therefore most active during the push-off phase of walking and running.

What are the Symptoms of calf strain?
The pain of a calf strain injury can range from a still cramping and tightness during the stretching or contraction of the muscles at the back of the lower leg, to immediate pain and even soreness when touched. In the worse cases, there can be acute stabbing pain and the person will be unable to walk meaning the muscle may have completely torn. Often bruising and swelling occurs.
