Where medicine is concerned, it's as much an art as it is science. You can have 2 doctors tell you to do something totally different to manage the exact same condition, and have neither one be wrong. This guy probably just wasn't a good match for you. Running on a treadmill is pretty high impact, I can't do it. But I can kick butt on the arc trainer (similar to an elliptical), and boy does it feel good to work up a sweat on that! I think it's because I can't run that it feels so liberating to fly on that thing. So if running truly is out for you, that doesn't mean you can't find another way to get the cardio/endurance in. My personal philosophy is the more you can vary your workouts, the better.
If I keep starting over, eventually it will stick, right?
