@ anon125256 - The article mentions some treatments that work for all causes of edema, like compression hose.
I had bad swelling in my legs and feet after my C-section from fluid build up. (I was able to wear my regular shoes all during my pregnancy, but I had to go home from the hospital wearing my slippers because my feet had swollen so during labor!) Right after my surgery, when I was still confined to bed, they treated the swelling with special leg wraps that inflated and deflated (a little like a giant blood pressure cuff, but not as tight) to keep my circulation up.
They got me out of bed as soon as possible, because movement is good for swelling, and encouraged me to walk around the mother-baby unit. (They won't let you carry your baby during this, so I pushed him ahead of me in his little plastic box!)
The other thing that they said would help was to drink lots and lots of fluids. It seems really counterintuitive, but drinking water helps your body flush fluids out, apparently.
