Just had a hip operation yesterday and was started on the physio today. Admittedly this only involved getting out of bed, but... Anyway, pushed through the pain (I'm a cyclist, after all) as I was encouraged to do, to such an extent that I blacked out and ended up on the floor. Not a good result. Though it was quite fun riding back onto the bed on top of a balloon.
There should be a moral to this story. Probably that cyclists capacity for pain is rather higher than that of the general population.
Cyclists perhaps, most women for another. My wife has had 2 hip replacements. I was with her the day after her second (that was privately done and local). I don't think I've seen anyone go from pink to grey in such short order as she was helped to the loo by the nurse. (Equally, she went from grey to pink almost as quickly when she had a blood transfusion a couple of days later.)
One of the reasons she was so diligent in the exercises despite the pain (and she doen't like to take any painkillers) was that a friend of hers, who is a GP, was adamant (and correct) that if she didn't do them, she WOULD limp.
She doesn't (at least as far as most are concerned), but another of our fellow villagers, seeing her walking one day, said "Have you had your hip done? Disappointed, my wife admitted she had, and asked how it showed. "Oh, it doesn't really, but I'm used to judging horses walks" came the rejoinder.
