Itching on the legs of varicose veins is a symptom of more serious varicose veins, indicating that the varicose vein staging is already at a higher level and requires surgical treatment. Because of the elevated blood pressure in varicose veins, it leads to dilation and tortuosity of the veins, and the inflammatory factors in the blood in the veins penetrate through the walls of the veins to the subcutaneous area and irritate the skin. The skin is also in a state of oxygen deprivation and impaired skin nutrition, which also leads to itchy skin on the lower legs. Surgery can completely cure varicose veins and the symptoms of itchy calves can be effectively cured.
