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.
Edema is sometimes caused by damage to or pressure within veins that causes them to leak fluid â blood plasma that is mostly water â into nearby tissue. (At other times, edema is caused by heart, kidney or liver disease that causes water to accumulate in the lungs, abdomen and elsewhere.) Fluid usually pools in the feet, ankles and legs, but it can also be more generalized throughout the body. Swelling can either disappear overnight or persist.
