Here is a link to an interesting article on the treatment of this painful and long lasting problem of the foot. I had this condition last year and it made so many parts of my life more difficult. The pain when I first got out of bed was eye-watering, and walking was problematic for several months. I wish now I had persevered with the needling of P7 as this is clearly indicated in the success of the treatments quoted in this study. See what you think?
