I agree with SandyRI about getting a good wc atty.

wc is a different animal when it comes to getting treatment and good care.
plus you have to think of your future and possible lost income from this injury. the possible spreading.....

if you are still working now don't talk about your injury to anyone at work, esp not management or HR dept. They are involved with WC to minimize all costs to the employer and the wc ins co.
coworkers will talk too so mums the word. just better that way. no details about the claim at all.

yes at some point wc will decide to deny, delay or close the claim.

If you haven't read on our WC forum that might be a good idea and there are info links in the stickys there too.

and since wc is a state thing read up on your state website about the rules and such.
unfortunately it is more complicated than the personal/private medical ins route.

But if your injury caused the RSD and you have good documentation, good drs, and the history of it all you should be ok -and a good caring assertive lawyer too.
