Calf strain

A tear of the calf muscles, common in running and racquet sports.

Overview

A calf strain is a tear of one of the calf muscles, often felt as a sudden pain in the back of the lower leg during push-off. Graded rehabilitation and a structured return to running reduce the risk of recurrence.

Symptoms

  • Sudden pain at the back of the lower leg
  • Pain with pushing off and rising on toes
  • Swelling or bruising in larger tears
  • Tenderness over the calf

Causes

  • Explosive push-off or sprinting
  • Fatigue and inadequate warm-up
  • Previous calf injury

Treatment

  • Early protection and pain management
  • Progressive calf strengthening
  • Graded return to running
  • Criteria-based return to sport
