Hi Chris,
Did they tell you to believe in Santa as well?
Isn't it amazing that our diagnosis can change so radically dependent on which doctor we see?
My three wise men (specialists) I first saw when I first had hip problems told me the following, in descending order:
Spec 1: It's old age, get over it
Spec 2: Far Out! What have you been doing? Your hips are on the way out
Spec 3: Your hips are fine, it's inflammation.
Spec 3 got it right, as 6 months later the more indicative symptoms of AS struck and led to the dx.
I guess you just need to go and see another specialist, and hope he/she get's it right. In their defence, we are complicated machines and I would hate to be trying to diagnose the problems!
