Saw your post and just had to write you. I have also been suffering with PF since last October. That was when it first became unbearable anyway.
I have been to the Dr. without much success. He made some inserts for my shoes and told me to buy Nike Air a full size larger than what I normally wear. This has helped alot, but I get so tired of wearing the same shoes. There is not a Birck store near me, so I keep trying to keep the pain down. I am taking Vitamin C and Advil for my pain right now.
I am glad to have found this site, lots of information to check out. I read the new postings every night.
Take care. Joyce
