Hello I last wrote in Nov. 2008. Since then a few things have happened. My Dr. and I felt that the physical therapy for the S.I. Joint Dysfunction was not fixing the pain. We looked at the previous MRI and saw a disk that could be causing the problem. He ordered a discography a few weeks ago. The results appear to show L4 and L5 are causing the problems. Low back pain. I have not seen the Dr. yet next week unless he gets a cancellation. But I am very excited about the results. The test was painful but I feel it will lead to a diagnosis and most likely surgery to repair the problem.  I will keep you posted thanks.
