Highlander, my CRPS was not work related, but over the course of 7 years it has spread, gotten so much worse and dibilitated me to the point that I am now in a hoveround. What I am saying is you need a VERY GOOD attorney who can do the research and defend your case WELLLLLLL!!! This isn't going away and if you are getting denied and shuffled around and bullied or mistreated in any way, you won't get the care you need.
Also, the earlier it's caught, the better the chance some of what happened to me might not happen to you....so denials and lack of care can drastically be detrimental for this condition.
Get the best lawyer you possibly can and be sure they are going to do a top notch representation for you.
Im sorry I don't have more advise, but this is my immediate thoughts after reading your post.
