Leg swelling can occur in any part of the legs, including the feet, ankles, calves and thighs. Leg swelling can result either from fluid buildup (fluid retention) or from inflammation in injured or diseased tissues or joints.

Many of the causes of leg swelling, such as an injury or prolonged standing or sitting, are common, easily identified and no reason for concern. Sometimes leg swelling can indicate a more serious disorder, such as heart disease or a blood clot.

Seek medical care right away if your legs swell for no apparent reason, especially if you have unexplained leg pain, difficulty breathing, chest pain or other warning signs of a blood clot in your lungs or a heart condition.
