Does anyone out there with this problem (post surgery) have difficulty with joint areas still "locking up" and with being able to "manipulate" the area into "moving". This is what I am experiencing. I have ongoing pain, with the tendency to relieve it a bit when it "crunches" as I move it around. Does this mean my fusion is unstable? I just had a CAT scan and xrays that the doctor says reveals that the fusion is "fused." Could this be a misdiagnosis? Also, what are the other possibilities? Torn scar tissue? Torn or sprained ligaments/tendons? I had lifting to do before the end of the school year, had several personal "movings" to do at home this summer, which all have resulted in chronic pain again with these SI joints. What do you guys think?
