Which test are you talking about? The HLA-B27 test is not diagnostic because the overwhelming majority of people with the gene will never develop disease and it's possible to have the disease without having the gene. The blood tests, ESR and CRP, can tell you whether you have systemic inflammation but don't tell you what's causing the inflammation. And up to 30% of people suffering from AS will never have an elevated ESR or CRP. Spinal damage characteristic of AS on xray is the closest thing we have to a diagnostic test. An MRI (with contrast) of the sacroiliac joints can help diagnose early AS before spinal damage is apparent on xray.
Ultimately I'm getting an MRI of the sacroiliac joints. I've already got severe spinal damage in the lower back, and I've never had anything done to look at the upper.
My concern about the sacroiliac joint MRI is that I use to have EXTREME pelvic pain and complications. But through years of sleepless nights and experimentation, I have been able to eliminate most of that pain through yoga and stretching. This was no easy task. I ripped my knees hamstrings several times in the process. Literally reshaping my body.
The tree-branch snapping sounds don't occur anymore. And the nagy pain that didn't alow me to sleep is gone as well.
Of course, I still have some complications in the pelivc region but Its nothing like it use to be up until a year ago. What do you think, will the MRI still show results?
