Hi, if anyone is considering a block, I would love you to check in with the foremost expert in CRPS in the U.S. (from what I can tell) who is Dr. Pradeep Chopra in Rhode Island. Have a consult with him first and see if he thinks a block is a good idea because I have heard that they can cause CRPS to spread. But he will have other ideas too which is what we all need, an overall plan and hope. Physical therapy and the right kinds of massage therapy are what we found extremely helpful. No medications ever helped, but we are going to try low dose naltrexone which has good research evidence on it.
