I always wear my shoes, however, unlike everyone else. That is key.
The kind of Chigong that helped me is a medical Chigong that has a lot of flowing movements, rather than the more static form, which does not do much for me.
One of the most amazing things for me was when I had a 'treatment' from the instructor. The entire time I could feel major pulsing in my bad foot, and afterwards I ran into a friend who said I looked like I just got back from a two week vacation. Supposedly the pulsing I was feeling was the 'stuck chi' or the barrier to the natural flow of chi. Just as a reference, my background is pretty hard core science (a doctorate in molecular biology) so I went into this as a skeptic.
