Just want to add that if the work comp has never SEEN it spread then can you ask for a referral from him to a doc with more experience with CRPS? If he hasn't seen it before then he's not really the most qualified because he is admitting that he is inexperienced with it. Just an idea in case you are unable to switch doctors with it being work comp (not knowing the laws in your state I don't know what your available options are).

If I were you...I'd see if you can find a WC attorney who specializes in RSD/CRPS. With ANY WC injury you are entitled to compensation for all injuries caused by the work accident, and that would include the spread of the RSD if you got RSD because of the work injury. If you hadn't gotten the RSD, then it wouldn't spread. But you should see if there is an attorney in your area who is familiar with RSD because they will be better equipped to fight for your needs and rights.

I am so very sorry to hear that it is getting worse. You really need treatment ASAP in the new areas if the RSD is spreading.
