TheCrew07, Mine was missed due to a few really odd facts. I injured my shoulder at the same time as I herniated 3 cervical disks. My shoulder tear was in the Supraspinatous (the uppermost of the 4 muscles that comprise the rotator cuff). On a normal man, the Supraspinatous is about 1/2" thick. Mine was 4" thick, mostly due to the work I did for a living. I learned that it's actually quite common for this muscle to be way over-developed in people that are in any of the pipe trades. The motion involved in using pipe wrenches is what does it. Right when I got hurt, tests were done on my neck and my shoulder. Shoulder showed good, neck showed as garbage. I could barely lift my left arm, but doctors kept saying "it's all radiating out of your neck." Finally, it tore the rest of the way through, showed up on an Arthrogram, and was operated on. The surgeon said that once he got in there, he could tell that it had been partially torn for a very long time, and that had it not torn the rest of the way, it likely would never have been diagnosed. I'm not saying Gamel's situation is like this, but when I hear people say "how do you miss a torn rotator cuff," my situation comes to mind. Medical imaging is wonderful science, but it's not infallible.
