I am so sorry about your fall causing CRPS. I know how awful that is. I was lucky and only got PN from injury.
While you are waiting for pain management, look up Ketamine infusions. This is the latest being done for CRPS and it has a good track record. Hard to find places in the US that works with this. Tampa Bay hospital is one of them. This Ketamine has had remission reports, through JAMA which is a medical journal with articles from around the world. This mag. keeps up with the latest in research. You might want to ask you doctor when you go see him. If he is has education about this, he may recommend something like this. I wish you all the best. ginnie
