Pressure socks have a certain effect and are very effective as a way to treat varicose veins conservatively. Its advantage is that it has no side effects, because it is a pressure gradient, and the pressure can simulate the direction of blood reflux. The pressure on the ankle is relatively large, and the pressure on the thigh is relatively small. So as to reduce the venous pressure along the direction of blood flow, improve the situation of venous congestion and prevent the further development of varicose veins.
