In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. The thigh is between the hip and knee and makes up the rest of the lower limb. The term lower limb or “lower extremity” is commonly used to describe all of the leg.
It can be caused by a problem with the circulatory system, the lymphatic system or the kidneys. Leg swelling isn’t always a sign of a heart or circulation problem. You may often experience swelling due to fluid buildup from being overweight, being inactive, after sitting or standing for a long time, or wearing tight stockings.
