Pain that occurs in the calf muscle on the lower part of the leg often is the result of a pulled or torn calf muscle. This is called a calf strain or a calf pull. It occurs when part of the muscle of the lower leg (gastrocnemius or soleus) is torn away from the Achilles tendon.

This injury happens during acceleration or changes in direction. The torn calf muscle may spasm, and contract forcefully. The toes will point down. Bruises show up in the foot and ankle due to pooling of blood from internal bleeding.

Calf Strains may be minor or very severe and physician grade the injury according:

• Grade 1 Calf Strain : The muscle is stretched causing some small micro tears in the muscle fibres. Full recovery takes approximately 2 to 4 weeks.

• Grade 2 Calf Strain : There is partial tearing of muscle fibres. Full recovery takes approximately 4-8 weeks.

• Grade 3 Calf Strain : This is the most severe calf strain with a complete tearing or rupture of muscle fibres in the lower leg. Full recovery can take 3-4 months and, in some instances, surgery may be needed.
