Go to the
RSDSA library, the 9th link and the top is "CRPS and surgery". Click on it and it will take you down the page to that section. There is a PDF about precautions to take when you have to have surgery with CRPS. It's the 2nd link in that section. The name of it is "Preemptive Analgesia in Elective Surgery in Patients with Complex Regional Pain Syndrome: A Case Report." The others are also worth reading in learning what may truly help and prevent it from spreading.
*hugs* to you and your family for all that you've endured and are still dealing with.
Hugs,
Karen
