People with venous insufficiency may have redness or skin color changes in the legs or ankles, varicose veins, leg ulcers or a hardening of the skin called lipodermatosclerosis. Venous insufficiency is a chronic vascular condition that impedes blood flow in the legs.
It's not a dermatological disorder, but its symptoms can make it appear so. Venous insufficiency itself is typically treated with compression stockings and elevation of the affected limb. Topical steroids or antibiotics may be prescribed to treat the skin-affecting symptoms.
