Hi Marg and welcome to the RA forum
You sound like a medical mystery to the Dr.s.
So its not AS but it is some form of RA. Im guessing that you have had all the appropriate scans and x-rays for them to come to this conclusion.
The only thing I could think of was maybe you need to up the Methotrexate (how many mgs do you take now?).
I wouldnt worry about having taken pred for a year - Ive been stuck on it for nearly 7 years straight now and am slowly tapering off because of starting Humira and its working so well for me.
You could also seek another Rheumy's opinion - again Im just throwing this out there
I wasn't much help, but I am sorry you are suffering so.
Hopefully someone who has had the same problems comes along and answers better than me
