Came across an article today in the New York Times that's quite timely: The Pain May Be Real, but the Scan Is Deceiving.
I'm currently enjoying my own medical odyssey - trying to get to the bottom of what's up with my back and leg pain and soreness. After seeing an orthopedist yesterday, my next step is to see a physical therapist who specializes in runners; I'll see him next week for a video analysis (!) of my running gait to check if there's something I'm doing that's causing the problems. No running for now, but I have been cleared to do biking; lots of spin classes in my future!
The lack of a clear diagnosis of the cause of the problem is a bit frustrating....but I'm hopeful that connecting with a good doctor will lead to some answers.
