I had my lumbar fusion April 29, 2010. Was given a large corset with many metal stays. For 5 weeks I had terrible upper back, neck, shoulder and arm pain. It made it almost impossible for me to lift myself out of bed or to even put my shirt on or take it off by myself. I found myself unable to find a comfortable sleep position. I was unable to drive. I finally called the office that fitted me for this corset and made an appointment. It turns out the metal stays were not fitted properly and the upper portion of the corset would catch under my shoulder blades and ribs every time I was in a seated position. The simple solution was for the metal stays to be bent properly. My one wish is that I prevent people from going through the same thing that I did. I spoke to 2 doctors about my shoulder pain and they gave me no explanation. I figured it out on my own.
