I was terminated from a job in March of 07. Due to a "non-work related" injury to my neck. I had a plate put in my neck and the case was settled. The injury was in the neck. The date of that injury was Jan. 06. In nov. 05 I had injured my shoulder. The dr. called it a strain to the trapezoid area. Recently I was told by my dr. that there is a problem with my rotator cuff. The pain is the same I experienced in nov. 05. Obviously there was a mis diagnosis. I also have lots of problems in my lower back. 3 disk are basically gone. The contract said the neck was the injury with the back and shoulders being affected. My question is because I signed a contract that says I could not hold employer accountable again with the neck injury. Does this now exclude the lower back and rotator cuff?
