The calf muscles run from the back of the knee to about halfway down the lower leg. Tightness in these muscles can cause soreness and pain.
People may develop tight calf muscles as a result of overactivity or insufficient stretching. Calf stretches can help relieve associated soreness and pain.
However, these stretches are unlikely to provide relief from other causes of calf pain — such as electrolyte, fluid, or nutrient deficiencies. In some people, calf pain results from more serious underlying medical conditions, such as deep vein thrombosis and peripheral vascular disease. These require medical attention.
