Varicose veins are caused by changes in the circulatory system. Due to changes in blood flow or the elasticity in your veins, blood begins to pool in certain areas rather than being circulated back to the heart. This leads to the blue or purple color of varicose veins. The additional pressure pushes against the vein causing it to grow bigger. In addition to changes in appearance, varicose veins may cause pain.

Soohyun Kim, MD, Surgery, answeredIt depends on the stage of venous reflux disease, and if you’re symptomatic from it or not. In some cases varicose veins are purely aesthetic. Other varicose veins are associated with symptoms such as blood clotting, leg pain, heaviness/fatigue, cramp, restless leg and swelling.
Varicose veins do not affect the body per say, but the fact that you have varicose veins is a sign you may have venous reflux disease. If you have venous reflux disease you may experience throbbing, cramping, leg pain and/or heaviness, fatigue, burning and itching. Symptoms can be made worse with prolonged sitting and standing. In serious cases, veins may rupture and bleeding may also occur.
Venous reflux disease may feel better with elevation or walking, but the disease may interfere with lifestyle and activity level.
Gabriel Lasala, MD, Interventional Cardiology, answered on behalf of Lakeview Regional Medical CenterVaricose veins signal that the venous system (the system of veins that return blood to the heart) is not working properly. This can lead to ulcers, bulging veins or edema (an often painful swelling of the legs).
