I'd venture to say that in a forum named "RSD Reflex Sympathetic Dystrophy" people probably know what RSD means
:-).
Thank you for going to the trouble of posting this so that it might help others. RSD can result from an IV that didn't get changed fast enough also.
I hope she will have gotten permanent relief, and I hope you will eventually post what did happen. Even if not permanent, sounds like even temporary relief in a case such as you describe is a huge achievement.
