I wonder why she never talks about it regardless of what the dx is?I am sure it could help someone even if not rsd suffers. Anyhow I have not heard of this med or others being on it. Maybe do a search on the search button on the boards to see if anything comes up here. It may not be someone with rsd but still could give you some view and possible things to ask the doctor. That has always helped me when I hear of others taking a med or doing a treament. It helps bring up questions to doctors that I see or if it could possibly helps and my concerns.
