Have you tried massage? I have P.F. and tendonitis in both feet. Six months ago, after climbing a lot of stairs, I feel sharp, pulling pain on both of my arches. The pain did not go away. After all the usual methods - ice, stretches, even a two-week stint of immobilization, which made them worse -I discovered that my muscles in my feet were totally locked up. I have had six sessions with a massage therapist, and my feet are finally feeling better.

I don't believe that you will have to live with this pain for the rest of your life. Please seek other doctors' opinions. This is a wonderful forum to talk to other people who know what you're going through.

Good luck!
