Understanding Varicose Veins
Varicose veins are abnormal veins that can occur in the legs. They can be small, thin purple-colored lines (called "spider veins") that lie just below the skin surface, or they can appear as thick, bulging or knotty veins. These varicose veins progressively worsen and often manifest into other symptoms if left untreated.
While many people think that varicose veins are simply a cosmetic issue, there is in fact often an underlying medical problem that causes varicose veins. This medical condition is called venous reflux disease.
Venous reflux, or venous insufficiency, is the impaired return of venous blood from the legs and feet, often manifesting as varicose veins, swollen ankles, aching legs, skin changes or venous ulcers. The condition is caused by failed valves inside the veins, which makes it more difficult for blood to return to the heart. This is why many patients can achieve temporary relief by elevating their legs.
One of the most common results of venous insufficiency is varicose veins. Varicose veins are superficial veins that have dilated in response to increased pressure due to incompetent valves.
Symptoms of venous reflux can include:
- Leg pain, aching, tired or weak legs, especially after long periods of standing or sitting
- Varicose veins
- Burning or itching of the skin
- Swollen legs and/or swollen ankles (edema)
- Color and texture changes of the skin
- Open wounds (skin ulcers)
