I don't know how much craniofacial dysplasia would affect the shoulder unless there is some sort of mid to upper cervical neck problem that may be stimulating the nerves which supply the shoulder.

I do know that the mood, sleep regulation, and pain center of the brain is the the amygdala. It is important for her to try and get good rest, and to manage her pain with the pain meds she was prescribed in order to keep her spirits high(er).
