Ok, mom evaluated by physician. That's good advice!

Other advice. On plane - drink a gallon of water (well, not quite but you get the picture). Take 2 capsules of horse chestnut (Prevention magazine reported on a Harvard study that proved it helps w/ reduced swelling on flights; I take 2 each time I fly). HC available at drugstores, Target, etc - over the counter.

I don't know what it is about Vegas, but I & my biz colleagues call it 'fat finger syndrome' - same could be applied to ankles. Drink as much water as you can; that helps.

This also helps - she may or may not want to do it. When she's back in the room, sit on the edge of the tub & run ice cold water over her feet.

The next requires some flexibility, but it works - I've tried this too. Lay on the floor w/ your legs going up the wall (back on the floor); scrunch up as close to the wall as you can get w/ your butt, w/ your legs straight up; stay there for 10minutes; blood/energy goes back down (helps to listen to tv while you're doing this to avoid boredom). Ok, it's not a great description but try it.
