Thanks for the posting your query at DoctorSpring.com
I have gone through the report and query that you have.And I would like to highlight two things Early morning stiffness and pain in the back and very well described shoulder pain mid thoracic pain etc' with high CRP and normal sacroiliac joint.
the CRP is high because of inflammation and where is it, in the spine. why is xray pelvis normal because there is no irreversible damage, what to do, please get HLA B 27 by PCR, which your specialist will ask/ order.
My diagnosis probable Spondyloarthritis axial form pending HLA B 27 report with high disease activity with high ASDAS CRP value.
if you have any query kindly feel comfortable to ask.
