Possible complications of varicose veins

Varicose veins are common and are not always associated with more severe health problems. However, they can become painful, unattractive and worsen over time. Varicose veins can cause legs and feet to swell, creating a sense of fatigue in leg muscles and throbbing and cramping at night. The skin surrounding the veins may also itch and burn.

These symptoms may be a sign of an underlying condition called venous insufficiency in which damaged or diseased valves result in backward flow of blood in your leg. Patients with venous insufficiency often benefit from medical treatment.

You should see a doctor if the varicose veins have become swollen, red or tender or warm to the touch.
