Thanks for the responses everyone!
ali12, the oil rub thing is out. Suzy says that would put her in pain for a week. She is all for moving around as much as she can to avoid severe stiffness and atrophy.
CRPSbe, your advice is what the doc told her to do, elevate her legs but didn't mention "above the heart" which makes much more since in which she is now doing, thanks!
fmichael, my wife may try an over the counter diuretic first to see if she sees results with it before moving to a prescription diuretic.
RSDLynnie, a lawn buddy sounds good. been pricing them.

Thanks again everyone and have a great day!
