My CRPS is from a WC case also. Every state has different WC laws. It is important that you get a lawyer ASAP. You do not pay WC lawyers upfront. They get a percentage of your final settlement which is set by your state.

Also remember that WC doctors work for WC not you. They look out for the insurance company not the injured worker. If your state allows for it, insist on choosing your own doctor (not one suggested by WC). Also a lawyer will help you get paid back for any out of pocket expenses associated with your injury (ie. copays for seeing doctors related to your injury- rheumatologist, etc). Many will also help you navigate applying for SSDI.

I've been dealing with WC for a long time. I'm also a medical provider. You will get screwed without a lawyer.
