Damaged valves in the veins can cause blood to pool in the leg and lead to swelling and discomfort. This condition is called chronic venous insufficiency, and can lead to skin damage and leg ulcers.
Symptoms of chronic venous insufficiency (CVI) include varicose veins; daily swelling of the leg; skin color changes around and above the ankle region; dermatitis; and, fragile skin - opens easily with minor trauma. CVI can be effectively managed by wearing gradient compression stockings daily.
The 30-40 mmHg knee length compression stocking is the most widely prescribed stocking for chronic venous insufficiency.
