FULL RANGE OF MOTION

I feel deceived by the WC doctor. During my visit with him, i was asked to raise my arms up/down/sideways. Because I was able to perform these tasks, he released me back to work full duty w/o restrictions. Despite feeling pain in my arms and hands, I still could defintely move them. Pain is subjective and I need definite proof of an injury. EMG/NCV tests were normal. My Jamar grip test faired extremely low with the L 10/10/10 and the R 15/10/10, but he didnt find that "objective".
My WC case is being denied, but i am appealing. What do I do in the mean time? Should I get a third opinion from another orthopedist and how does WC weigh the facts?
Thanks
