Hello Carole, The Donjoy Dura Soft Shoulder Wrap/Back Wrap can be used for both the shoulder and back. It is a 12x13 square ice pack that can be wrapped around and secured with 2 velcro straps. This is not to be used as a sling.
Edema is swelling of both legs from a buildup of extra fluid. Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
Fluid overload, which causes swollen legs like these, happens with both heart failure and kidney disease. Fluid overload is most frequently caused by heart failure. As the heart weakens, blood flow returning to the heart slows, backs up in the veins and causes fluid buildup in the tissues. Heart failure also affects the kidneys, resulting in less efficient elimination of sodium and water. The retained water increases the fluid congestion.
