Varicose veins are the three main clinical diseases including varicose saphenous veins of the lower limbs, varicose veins of the spermatic cord, and varicose veins of the esophagogastric fundus. For patients with varicose veins, hot compresses are not allowed, especially in the case of double lower extremity saphenous vein varicose veins, it is absolutely forbidden to do hot compresses or heated microwave physiotherapy. The reason is that hot compresses can easily accelerate the blood flow in the veins of the lower limbs, which can cause the blood flow in the varicose veins to gradually increase and the degree of bruising to increase, thus indirectly aggravating the severity of varicose veins. Especially some patients think that varicose veins can be improved by applying hot compresses or heat therapy to accelerate blood circulation. On the contrary, varicose veins need warm water for bathing to resist the rate of venous blood flow and to reduce the degree of varicose veins. Therefore, patients with varicose veins should not use hot compresses and should try to wear lower extremity venous compression stockings or take surgical treatment.
