give it a few days I would say. Although I was up and about after my op, and I did do a ten minute walk to the shops on day 4 post-op it left me feeling very tired and strangely breathless. By a week after I was fine, driving and feeling much better about walking distances. I know it is individual, but be prepared for even a short walk to make you feel pretty tired in the early days post-op. Hope this helps x
