Glad you found this site, they're (we're) great at sharing personal experiences with this horrible condition. I'm really sorry you have to experience it.
I have no experience with work comp. but I agree you should be careful and probably do not use full real name on here.
Do keep looking for the right doctor, get new referrals whatever. Especially look at pain management offices. Be careful of the ones that exist only to dispense oxycodone etc.
The good ones will screen for drug shoppers. Try to ask when you call if there's a doc. with experience with RSD. Who gave you the diagnosis, maybe they can help.
There's no cure, but some drugs can help depending on the person. Definately AVOID ICE on the affected limb! Look at RSDHope.org as well b/c there are many articles and correct information there.
