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.
