Varicose vein stockings need to be selected according to the degree of severity of the condition, as well as different lengths and appropriate models. 1. Mild varicose veins: you can choose the health care type of compression stockings, which generally have lower pressure at 15-20mmHg. 2. Moderate varicose veins: they are accompanied by superficial phlebitis or skin pigmentation. In this case, you can choose secondary compression stockings with a pressure of 23-32mmHg. 3. Severe varicose veins: In addition to varicose veins, skin ulcers and lymphedema may be present, so it is recommended to choose grade 3 stockings with a pressure of 34-46mmHg. In addition, it is necessary to choose different lengths and models according to the circumference of the calf and thigh, and if the patient’s symptoms worsen, it is necessary to consult a doctor in time and do not delay the condition.
