Can you do chair exercises? There are several places on the web that show them. pump your legs like you are riding a gentle bike. pick your legs up and down. stretch them. getting that fluid moving should help you a lot. Compression hose wouldnt be a bad idea, nor would massage to help the lymph fluid drain. Can you sleep with your legs higher than your heart? use one of those foam blocks?

Either way that has to be uncomfy. I hope you feel better.
