Leg swelling related to fluid buildup. Leg swelling caused by the retention of fluid in leg tissues is known as peripheral edema. It can be caused by a problem with the circulatory system, the lymphatic system or the kidneys. You may also experience swelling due to fluid buildup after sitting or standing for a long time.
Leg swelling generally occurs because of an abnormal accumulation of fluid in the tissues of the lower extremity. The medical term for leg swelling from excessive fluid in the tissues is peripheral edema. Persisting indentation of a swollen leg after pressure from a finger is known as pitting edema.
