Leg Swelling

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

Sometimes leg swelling may be a sign of a more-serious disorder, such as heart disease or a blood clot.

Complications include difficulty breathing, chest pain or other warning signs of a blood clot in your lungs or a serious heart condition.

It can be caused by a problem with the circulatory system, the lymphatic system or the kidneys.

Leg swelling caused by the retention of fluid in leg tissues is called oedema.

Other cause could be due to being overweight, being inactive, after sitting or standing for a long time, or wearing tight stockings.
