Eileen – you will need to keep elevating and icing as long as you are NWB. As soon as you start PWB, you will see an improvement in circulation, which will recirculate the fluids in your leg and bring down some of the swelling. When you go FWB, then you engage all of the leg muscles and that really helps push the fluids and bring down the swelling. And yes, my foot turned purple at first every time I put it down. That problem also resolved itself with FWB. Your exhaustion is something a lot of us complain about. It takes a LOT of energy (and calories) to heal a broken leg! So, everything you are experiencing is pretty typical.
