Varicose veins are vascular diseases of the venous system, which often take a long time to develop and are characterized by initial venous vasodilation. As time goes on, the lower limbs will gradually become sour, swollen, painful and weak. The longer time goes by, the skin of the leg will begin to change color and become calm, blood vessels will rupture, and the skin will fester, forming old rotten legs. Others may be complicated with thrombophlebitis and pulmonary embolism. You should pay more attention to rest, and you can check your nursing regularly to avoid aggravating your illness. If it becomes serious, don't hesitate. Timely treatment is the most important, because early treatment of varicose veins is beneficial to the condition and the cost is relatively low. The more serious it is, the more difficult it is to treat varicose veins thoroughly, and the cost will increase. At present, the only way to treat varicose veins is through surgery, including surgical stripping and laser minimally invasive treatment. Laser damage is less, more convenient, the overall curative effect is good and the curative effect is exact.
