My hands usually well when I walk too long on a very hot day, but not often. My feet are constantly swollen and I take diuretics for them. If you're not into taking meds make sure that you keep your feet above your heart (lie in bed) a lot. And when you are sleeping keep your feet on the bed because sometimes while we sleep they slip off the bed and dangle which is not good. Cranberry and pomegranate are good, too, but make sure it's pure juice and not concentrate. -nod nod-
About your hands...I don't know what to say... I don't have that problem much.
