It is indeed a very extensive approach. Can I ask what medium you are using for phonophoresis/iontophoreis and would you do both or have you found one method better than the other. I have found the simplest and quickest way to provide relief is to use ultrasound, massage and building up the intrinsic muscles of the foot. Check the footware to ensure there is adequate arch support present. Taping is a good method to see if arch support is required. I also have found a lot of people get relief by rolling the traditional ribbed Coke bottle with the under their foot gives relief. I have not tried neural mobilisation as Bernard suggests but it also is a quick and easy technique to apply and results should be easily assessable.
