I was diagnosed with RSD in my left foot approx 20 years ago and listened to my stupid doctor and went through RSD hell. But that's not important. Here is the treatment which I found thanks to US governmental agency and which helped me tremendously: DAILY LOW DOSES OF ULTRASOUND = 5 minutes a day without any pain. I don't remember the ultrasound frequency but it was very low and tested by the doctors at UC Davis, so they can advise you. Now I am using only patches infused by capsaicin and belladonnae radicis, witch I found in Europe. I don't feel the pain and I can walk again. No pills, nerve blocks or other expensive treatments are needed and I went through all of them. Ultrasound works on lower extremities and for the upper part of your body supposedly laser is helpful. I hope this will help your daughter or somebody else.
