water retention

Hey Ladies! So I've been struggling with swollen feet and legs over the last couple months. There is what they call "pitting" (fingers leave a dent in skin when pressed) and the extra blood leaves my shins feeling very sensitively bruised. BP is just fine, doctors keep saying I need to elevate them to relieve the pressure, but it doesn't seem to help much. I've tried wrapping them, but it makes my "bruises" worse. Any of you out there have any tricks that are life savers ??
