I had a normal SI joint x-ray after 7 years. I have read that it can take up to 10 years before there is any radiographic evidence. You mentioned that your original pain was more mechanical. Maybe your AS started in 2005. I am not sure why the doctor said that. I certainly can't debate her on the topic. I thought that if there isn't any evidence of structural changes but you still had the symptoms that it was undiff. spondy. as opposed to AS. That may not be AS but it is still inflammatory arthritis. The fact that you don't feel better with activity and feel fine in the morning is a red flag. You may have not have AS. What peripheral joints are affected? Are they the more common AS joints?
