Inflammatory? You need to know if is inflammatory and a sedimentary rate, RA factor, and nuclear scan can rule this out. If not inflammatory, the pain pattern suggests sacroiliac joint (sij) dysfunction, which cannot be seen on ct and MRI scans nor any other imaging study, as reported in the medical literature. Diagnosis of sij disorder is done by means of a fluroscopic guided diagnostic block of the sij.
Inflam. Arthritis? Have you seen an rheumatologist? With multiple joint complaints, it is reasonable to be worked up for an inflammatory condition similar to rheumatoid arthritis. These conditions do not necessarily show up on ct or MRI scans.
