Hi does anybody know much about this??
I have lupus and aps and now being checked for this as I have SI joint pain and previously had sacroilitis on X-ray with narrowing and sclerosis of SI joint. I get really bad pain in my sI joints and wake in the night and morning stuck on my side unable to move as my lower back has ceased up.
I’m sure I’ve had the hla b27 year before but rheum can’t find it so gonna repeat. I’m sure i had it and it was negative. Can it be negative and stillhave AS??
He’s sending me for an mri scan to see what happening.
