Both my GP and the WCB Dr said that I presented like I had SI joint dysfunction, and they both said that SI wasn't the problem. So how is it DX'd? Can it be seen on an MRI? If not, what test are done? MRI and a bone scan were all that I had done, and both Dr's already had ruled out the SI before that, even though they said that it presented as that. So it really has me wondering, how do doctors DX it?
