Knee pain

I have been reading your book and trying to apply it for a couple of months now. I have had off & on lower back pain for years, but not any more! I can really feel a difference in the strength of my back.(I just turned 50) The only problem is that now I am having difficulty with my knees, which I never have before. They feel achey and stiff most of the time, especially whenever I am on my feet for any length of time. If I have to bend my knees or kneel at all I feel like they are very vulnerable. I know my hamstrings are probably quite tight - I'm trying to do the exercises for that. By the way, I checked to see if I walk on a line.and I do using my natural gait. (I walked on a freshly raked baseball diamond with chalked lines.) Not sure what to do about this. Any ideas?

1. Did you succeed in kidney-bean shaping your feet? That's important for knee alignment. Check your knee alignment by bending your knees some and taking an aerial view of how the plane of the bend of the knee compares with how the foot is facing. Ideally, you want your knee bending the same way your foot is facing. 2. Did you make your foot and leg transitions too rapidly? Sometimes people get sore from trying to transition to an ideal arrangement too abruptly. 3. The traditional PT approach of strengthening the quads also has merit in this situation. If none of these measures help, go see a health professional (the relevant ones that come to mind are acupuncturists and PT's). Best of luck! Glad to hear your back pain has responded so well - fantastic!
