Hi Nikki -
So sorry to hear of all your troubles - that sounds so painful! As for Chi Running, yes, it’s possible it can help, but you really need to take it slowly and easily, especially if you have habits that need unlearning. The best thing to do is get together with an instructor, if there is one in your area, and have them watch you run. They will be able to assess what your gait is like and how it might be contributing to your issues. If you don’t have an instructor in your area, there are some who offer video analysis online. If you have not yet gotten a copy of the Chi Running book and/or DVD, I highly recommend so you have an idea of how it works.
The beauty of Chi Running is it teaches you how to relax your lower legs and instead of using them so much for propulsion, you use them for momentary support between strides. And speaking of strides, shortening your stride length (if you tend to overstride) will help alleviate overuse of those calf muscles as well. A faster cadence (170-180) also helps. All of these aspects are part of what you learn in the Chi Running technique.
Good luck and please keep us posted!
