I, too, am overweight and awaiting replacement surgery. I am 5'6" and, the last time I weighed myself I was 270 lbs. I am in so much pain right now I walk with a cane only short distances. I cannot shop for groceries or anything else. We have purchased a wheelchair and I am able to get around with that. My doctor advised me to "get smaller," before my surgery, but he didn't say he required it. I'm still on a waiting list and was told earlier this week that the earliest time would be December, but it'd be more likely to be in January or February. I am in more and more pain all the time. I'm currently taking Vicodin for the pain, but it isn't working too well. I'm going to contact my PCP for something different. But, I still need to be able to work, so I can't take anything that makes me loopy! I was working out and losing weight, but I can no longer get onto my elliptical machine. I started swimming but getting from the car to the pool and back is becoming too painful. I know I would feel better at a lower weight, but it just isn't that possible while I'm in so much pain. I'm looking forward to having my hips done and being able to exercise and lose the weight. And, in a year's time I want to walk along the beach - pain free!!
