11 Leading Causes of Leg Pain and Sore Calves

Muscle Sprain, Strain or Tear

These conditions occur when either a muscle or the tendons that attach to it have been damaged in one way or another. A sprain refers to damage to the ligaments that connect bones in the leg. Strains indicate damage to a muscle or tendon, while a tear can occur in a muscle, tendon or ligament. When muscles are suddenly placed under heavy loads or the individual over stretches tendons, ligaments or muscles through sudden movement, it can cause strain. Hamstring strains and tears are very common and are a frequent cause of leg pain.
