Does anyone have any tips that helped their swelling go down?

I am elevating my feet at night as much as I can. I also put a box under my desk at work, so my feet are semi elevated during the day. I drink plenty of water but nothing seems to be helping. My fingers, feet and legs are starting to look like stuffed sausages.

I will be 37 weeks on Sunday, so not much longer, just want to find something to help.
