Sits Down Floored after trip to the Doctor

I went to the Workman's Comp Doctor. I was expecting the news that the right is doing great and the left might get a bit better with work. I have been told the left is not going to get any better actually it could get worse. I have been given the option of this Doctor doing the surgery that did not go right the first time. I have a fifty percent chance of it getting better and the rest is the same or worse. I am left handed, this is my left arm, I am desperately trying to reach my primary care Doctor and my heart Doctor to get their advice on this.
