Dan,

Welcome to the forum. Sorry to hear about your situation. This place is good resource for information and support.

Yes, it is very possible that the fall started the CRPS (RSD). Sounds like your doctors agree. It doesn't take much trauma at all to start the CRPS process in motion. It is a very misunderstood condition, even by professionals.

Dr. Schwartzman is one of the best doctors in the country for this condition, so you are seeing the best.

Keep fighting for the benefits you deserve. I assume that you have legal representation for Social Security Disability? Between WC and SSDI, it can be a battle!
