Hi Karen, I was in a bad car wreck in '98 and no radiographic evidence showed on my x-rays or MRIs. The only thing they saw was where my back was broken, I was under the care of an ortho for the next few years, I went to him in 2000 complaining that my back pain was increasing in intensity and the x-rays showed some erosion in the SI joints, so he Dxed me with sacroilitis and started me on steroid injections in the SIJs, in 2002, he recommended surgery to fuse my SIJs because they'd gotten so bad, he actually scheduled the surgery and I backed out...so for me, at 2 years from the onset of symptoms there was radiographic evidence but I wasn't Dxed for another 5 years for a total of 7 years...
