You have my sympathy and wishes for a good run. I had PF in my right foot which worsened as my training program for my first half-marathon increased. I tried the Strassburg sock, orthotics, rest, increased stretching and PT, but nothing seemed to significantly reduce the pain. Finally, I consulted with a podiatrist who also was a marathon runner. (It took some doing to find him!) We spent a lot of time discussing my running habits, my training program and the nature of the pain. Since I had already tried several of the recommendations he would have made, he suggested a cortisone shot. The shot was NOT fun and you can't run for a couple days afterwards, but the change was miraculous! The pain was gone. In order to avoid a repeat, I've been diligent with pre-run stretching, replacement of running shoes that are starting to break down, and post-run stretching and icing. So far, so good. It's been 2 years since my PT injury and I'm in training for my first marathon. Good luck to you!!
