So sorry you are having such pain with the CRPS. There are alot of medications that can help. don't give up and get to a doctor that specializes in this. After your pain in under control, consider going to an oral surgeon, who could put you to sleep to remove the broken off tooth. That way you won't feel any pain from that. Removing the broken tooth will be important to do to prevent infections in your jaw. I hope you get some good help soon. Let us know on NT how you do. I care about you. ginnie
