Superficial varicose veins of the lower extremities can develop to a certain degree and can show symptoms of edema, which can be basically graded as C3 level. Superficial varicose veins, itself due to the incompetence of the valves of the superficial veins, lead to poor blood flow back into the deep veins. The human body is divided into the venous system and the arterial system, which reaches all organs of the body, including the lower extremities, from the heart. The venous system returns blood from the lower extremities to the heart, so when the valves of the superficial veins become incompetent, the blood from the superficial veins cannot flow back into the deep veins, resulting in varicose veins and increased inlet pressure, leading to the infiltration of blood and water into the intertissue fluid to form edema. The symptoms are more typical for patients with varicose edema of lower extremities, which is called morning light and evening heavy. Patients often get up in the morning when both lower limbs are very easy, and in the afternoon, due to the effect of gravity, after a day of labor activities, the water pressure into the lower limbs increases, and the feeling of heaviness and weakness in the lower limbs becomes more and more serious, and the typical performance of varicose edema is morning light and evening heavy.
