Varicose Vein Myths and Facts

Myth: "Varicose veins are only a cosmetic problem"

Fact: Varicose veins are a chronic venous disease. Faulty valves let blood pool in the legs, raising pressure in the veins. LEDAS stresses that it is a misconception to see them simply as protruding veins. Left untreated, the condition can progress to swelling, skin darkening, hardening and venous ulcers, and is linked with clotting problems. See complications of untreated varicose veins .

Myth: "If I can't see bulging veins, I don't have a vein problem"

Fact: Many symptoms are invisible. Heavy legs, a "bursting" feeling in the calves, ankle swelling, night cramps and itchy ankles can all come from reflux in veins hidden under the skin or between muscles. A duplex ultrasound can find it. Try the self-check checklist .

Myth: "Only older women get varicose veins"

Fact: Women are affected more often, partly due to hormones and pregnancy, but men get varicose veins too, and they can start in young adulthood. Family history is a major factor: according to LEDAS, with one affected parent the chance is about 25% for a son and 62% for a daughter, and with both parents over 90% regardless of sex.

Myth: "Crossing your legs causes varicose veins"

Fact: There is no good evidence for this. The real issues are heredity, hormones, age, weight and long periods without moving the calves – sitting or standing. Changing position and moving often matter more than how you sit.

Myth: "Running and exercise make varicose veins worse"

Fact: Exercise that works the calves, such as walking, running, cycling and swimming, helps the calf muscle pump move blood upward. See sports, running and your veins .

Myth: "Varicose veins will go away by themselves"

Fact: They don't. Varicose veins are progressive. Pregnancy-related veins may shrink after birth, but the underlying tendency remains. Lifestyle changes can ease symptoms and slow progression but cannot repair damaged valves. See can varicose veins go away on their own .

Myth: "Compression stockings cure varicose veins"

Fact: Medical compression stockings improve circulation and relieve symptoms. LEDAS describes them as conservative care that supports treatment, not a main treatment. See do compression stockings cure varicose veins .

Myth: "Treatment means painful surgery, general anesthesia and a long recovery"

Fact: That describes old-style stripping. At LEDAS, treatment combines EVLT and ultrasound-guided sclerotherapy under local anesthesia only, with no incision and same-day discharge. A pulling feeling for 1–2 weeks after laser is common. See why LEDAS moved away from stripping .

Myth: "If you close a vein, your leg loses circulation"

Fact: The treated vein is already working against you, sending blood the wrong way. Once it is closed, blood reroutes through healthy veins, mainly the deep veins, which carry most of the return flow anyway.

Myth: "Once treated, varicose veins never come back"

Fact: Treated veins that close fully rarely reopen, but varicose veins are a chronic disease and new reflux can develop in other veins. That is why LEDAS includes a relapse prevention program with ultrasound every 1–2 years or whenever an overseas patient visits Korea.

Myth: "Spider veins are always harmless"

Fact: Often they are, but sometimes they signal deeper reflux. See are spider veins cosmetic or medical .
