Definition of varicose veins: Varicose veins are seen as twisted, earthworm-like bruises on the legs. They are generally more common in the lower legs. The lower the veins in the body, the higher the pressure, so varicose veins tend to occur in lower positions. Prevalent people: Occupations that are standing for a long time, such as hairdressers, hostesses, flight attendants, nurses, teachers, etc., are the most prevalent people with varicose veins; in addition, women with increased pelvic pressure during pregnancy are also susceptible; heavy laborers are also included. Complications of varicose veins: One complication is dermatitis of the skin, which often appears as eczema, and the patient feels itchy, mainly in the lower legs. Another dangerous complication is thrombosis. In addition to pain, 10% of patients with superficial vein thrombosis will develop deep vein thrombosis, which may even be fatal if pulmonary embolism is formed. Another critical complication is hemorrhage, that is, accidentally touching the place where the pressure of blood vessels is particularly high, resulting in blood vessel rupture and bleeding, and this kind of bleeding patients often feel no pain.
