If this message drive any point home, it is that PF strikes people very differently and that remedies work very differently for people also. I am one of those people for whom Birks have been a godsend. I have worn them almost constantly since December and I definitely have improvement. I am far from recovered. I do not go on my daily 3-4 mile walks anymore. But -- I can manage to get through the day and do what I need to do without tremendous pain. I take a lot of glucosamine sulfate and vitamin C, but I credit Birks with being a major part of the solution.
Many people have posted to the board that they are NOT able to wear Birks, not even for an hour or two, without tremendous pain. For me personally, they have eliminated about 50% of my pain -- and have made a world of difference.
