Hello M,
Yeah... being on the "crazy pile" sucks. Hopefully you can get this sorted out... fact that you are not HLA B27 positive or evidence of fusion probably clouds the issue for some rhuemies if they are "old school".
Best advice if you believe AS diagnosis accurate is to learn more and work with educating the doctor.
If the diagnosis changes, what does that do with the treatment you now have? Will it all of a sudden change drastically?
Best to you,
Tim
