KS, I'm glad to hear your surgery went so well. My surgery was on Tuesday, also, and by Friday, my surgeon decided to send me home on Saturday. I thought it was a little soon but I realized later that it was more of an emotional reaction than a physical one. It is very natural to feel a certain sense of fragility in the days after surgery but your confidence will improve with every walk. In most ways, you are far less fragile now than you were only a few days ago. Besides, hospitals are full of sick people and you just need rest and exercise (lungs & feet) unless you have a complication that would keep you there. Rest and exercise you can do more comfortably at home. Let us know how things are going.
