Venous insufficiency is caused by a series of disorders in the vein including when the valves of the veins fail to function properly. This interferes with venous return and causes blood to pool in the veins. Venous insufficiency can become more chronic and lead to spider veins, varicose veins, phlebitis, blood clots, and changes in the skin. The most serious disorder is a venous leg ulcer. Chronic Venous Disorders (CVD) is a collective term used to describe a long-standing condition involving impaired venous return in varying degrees of severity.

A feeling of discomfort in your legs may be a sign of an underlying venous disorder. These symptoms include tired and achy legs. You may experience them especially when sitting or standing for prolonged hours.

Symptoms of CVD include:

• Edema (swelling)
• Feeling of heaviness in the legs
• Pain or cramps in the calves
• Skin discolorations
• Dermatitis (skin problems)
• Dry or weeping eczema
• Venous leg ulcer
• Visible Veins
