Venous disease or venous insufficiency is a condition where the veins in the body, particularly in the legs, have difficulty returning blood to the heart effectively. This condition arises from various risk factors that cause weakened or damaged vein valves. The damaged valves cause poor circulation with blood pooling in the legs leading to increased pressure. Symptoms such as bulging varicose veins, swelling, fatigue, heaviness, itching, burning, restless legs, leg pain, skin discoloration, and open sores are caused by the increased venous pressure. The main contributing factors that lead to vein disease include age, multiple pregnancies, genetics, obesity, prolonged sitting, or extended periods of standing.
