Best wishes for a speedy recupe from Michigan, USA. I had that operation 54 years ago. I don't know if it was from lifting too much around the farm, or just a weakness from birth that caught up with me when I was 12. Back then I was in the hospital for a few days; (Americans spend time "in the hospital", not just "in hospital"). I see that the word is, with the current approach, you should be "out of hospital" in no time.
