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.
The presence of edema means that there is more fluid than normal in the space between the cells. Usually, this extra fluid comes from the fluid inside the blood vessels. Edema of any cause is often worst in the legs and ankles. When weâre sitting or standing, gravity pulls the water inside blood vessels downward.
