Compression stockings are specialized hosiery designed to help prevent the occurrence of and guard against further progression of venous problems such as edema (swelling), varicose veins, and leg fatigue. By compressing the surface veins, arteries and muscles, the circulating blood is forced through narrower circulatory channels. As a result, the arterial pressure is increased, which causes more blood to return to the heart and less blood to pool in the feet.
