I. Definition of varicose veins Varicose veins in the lower extremities refer to the elongation of superficial veins under the skin of the lower extremities, meandering and tortuous, with stagnant venous blood. They usually appear in the inner, front and back of the lower leg, sometimes extending to the lateral side of the ankle, and in severe cases to the inner thigh. The main cause of varicose veins is venous valve dysfunction and reduced elasticity of the venous wall, which causes poor blood flow back into the veins and causes them to dilate into varicose veins. Varicose veins in the lower extremities are very common and occur in people who have long standing jobs or manual labor, such as teachers, medical personnel, flight attendants, police officers, salesmen, hotel greeters, factory technicians, etc. Pregnancy, long-term chronic coughing, habitual constipation, etc., are also predisposing factors for the disease. Second, the symptoms of early varicose veins swelling of the ankle and wrist, heavy fatigue of the lower limbs, weakness, accompanied by a slight feeling of muscle throbbing or soreness, and even cramps and tingling of the lower legs, etc. From the skin surface of the lower limbs, there will be like earthworms or flesh-like protrusions. Further development of the disease to the middle and late stages will appear dermatitis, skin discoloration or even breakage. In the discovery of the above early symptoms, should be early consultation, early treatment, and strive to achieve “four fast” that is, fast detection, fast diagnosis, fast treatment, fast results. Only then can we get rid of the disease. Varicose vein stockings change the previous simple stripping of the superficial varicose vein and high ligature or compression bandage, using a special process to produce a certain gradient pressure on the lower limb from top to bottom, with the greatest pressure at the ankle and gradually decreasing upward to the least pressure at the root of the thigh. The different pressure difference transmits the pressure to the veins through the muscle tissue to counteract the intravascular venous hypertension, promote venous blood return and improve the symptoms of intravenous stasis, thus achieving the purpose of treatment. Soft, light, multi-effect massage, it can promote blood circulation, reduce fat accumulation and can eliminate excess toxins. Fourth, how to prevent varicose veins 1, try to smoke less, eat less greasy food, less alcohol, because all of these have a bad effect on the blood vessels. 2, as much as possible to move the lower extremities to promote the venous blood flow back up to the heart. When standing or sitting, every half hour should be slightly active enough to keep the blood flow back to improve blood circulation in the lower extremities. 3, elevate the lower extremities to help blood return to the heart and reduce fluid stagnation in the lower extremities, which should also be done after each exercise, which will help return to normal blood circulation and avoid blood stagnation. 4.Adhering to physical exercise can keep the blood circulation system working in a healthy way. 5, pay attention to the protection of the legs to avoid bruises or abrasions. 6, should not sit cross-legged for a long time, otherwise it will affect the blood circulation. 7.Should not wear high-heeled shoes (or too tight shoes) for a long time, which will affect blood circulation. 8.Should not expose the legs to too much sunlight or soak in too hot water, which will expand the blood vessels in the legs.
