Some doctors I swear. lol So what since your daughter is 13 she's to young to hurt,it has to be some sort of mental stress,or something wrong in that manner. I would be grilling the doctor about what all he has seen and make sure he's not in it just for the nerve block money. I hate to sound that way but it's totally eceptable to know everything about the person treating your kid. It's your KID. Come on.
If you have a pediatric neuro I would look into his/her office. See how many patients of theirs have been diagnosed and are being treated for rsd. Any one who is used to dealing with children are usually better when it comes to communicating with kids. It can make your daughter more comfortable and you too. Some states have state websites where you can put in the doctors name and or office if more than one doctor, and see if there has been any big complaints,been sued,investigated for malpractice and so on. My state has a website like that and it really can help when you are looking into a new doctor to make sure you are making the right decision for you and your family. Between that and calling the office, you can always make an appointment for a consult. Consults aren't just for the doctor but for you too. You can make consults to talk with the doctor and see what kind of practice he/she has and how long they've been treating crps,etc. Just be your own advocate. Stand up for your daughter. Some doctors really don't listen to the children so you kindof have to be her voice too. Although your daughter is the only one who knows how she feels,truly. She needs to be comfortable with them and be able to be open and say how she feels.
If it were me I would think about seeing someone who deals with children,only children. I hope I've been some help. You and your family will be in my thoughts. I hope everything goes smooth for her on friday
Take care and stay warm,
