I had one 8 months ago called a minuteman procedure, some call it a lumbar fusion. It did not help me at all, actually it made things worse. Pain Dr. ordered a CT scan at my last visit in March. It took a month to get the scan scheduled, results were sent to the Dr five days later but I never heard from their office. I finally called them after waiting a month and two more calls before hearing from anyone. I am scheduled for follow-up next week. Since I have so many issues with my back, I have no idea what he will suggest. I am not looking forward to what I think may be next.
