Protruding veins, also known as varicose veins, are formed mainly because of valve regurgitation, which results in high pressure. Therefore, wearing medical elastic stockings, taking medications to improve the function of veins, such as Mai Zhi Ling and Avalanche, and avoiding prolonged standing and standing have certain effects. However, when thrombophlebitis occurs in varicose veins or ulcers form at the distal end and bleeding occurs in the distal saphenous vein, early surgery is recommended. Due to anatomical relationship, varicose veins mostly occur in the lower extremities, due to the incompetence of the saphenofemoral vein valves in the lower extremities, thus causing venous regurgitation, forming distal high pressure and varicose nodules, which mostly occur in the inner thighs and the saphenous vein travel area. The varicose nodules tend to be more obvious because of the higher pressure in the distal calf veins of the limbs, and the nodules are characterized by a soft texture, which is more obvious in the standing position and can disappear in the lying position.
