I had my last MRI in May of 2007. I have struggled with renewed back pain since September of 2008, but when I visited with my spine surgeon back in January, he went off my old MRI and said that it's not a surgical issue, that I just have sciatica and I will have to "live with it." After 14 sessions of PT and visits with the chiropractor, I asked my family doc for another MRI b/c of the new symptoms, but she refused b/c of the spine surgeon's report based on an MRI over two years old!
Just how often should someone have an MRI? Is the spine something that changes dramatically over a short period of time, or is it pretty static? I would think that they would want all the info before making any further treatment decisions, but then again, that would make sense, huh?
