The blood vessels on the soles of the feet are obvious in two ways: 1. The blood vessels on the soles of the feet are obvious but there are no vascular tortuosity and no skin color changes, this is a physiological change. Because the sole of the foot is far away from the heart, the pressure of the venous fluid is higher when standing, so the blood vessels of the sole of the foot will be obvious. 2, the blood vessels of the sole of the foot are obvious at the same time accompanied by the tortuous blood vessels, sometimes even earthworm-like changes, also accompanied by changes in skin color, swelling of the lower leg and soreness and discomfort, this situation is due to long-term excessive pressure on the lower limb venous valve insufficiency, resulting in reflux to the vein In this case, we should perform ultrasound examination of the veins of the lower limbs to determine the function of the valves in the veins of the lower limbs and treat them accordingly.
