Hello and welcome to the forum - my name is Alison, I am 13 years old and I suffer from RSD/RND in my left leg and right arm, if you ever want to chat I am here!!
I live in the UK, so don't know exacly what Dr Sherry does in his program but there is a similar program that I am going to start in July. I believe that they retrain your nervous system to behave in a "normal" way, they also deal with ROM (Range of Movement), Desensitise your limbs etc.
Here is a video about a girl named Alessa that went on Dr Sherry's program and she made is an almost full recovery!!

In the video the girl stayed at the hospital on the ward whilst she was having the PT as she was from out of town. I think it all depends how close you live from the hospital as to whether or not you are able to travel home and back to the hospital everyday. Her parents also stayed at the Ronal McDonald centre whilst she was having some of her PT
Hope this helps
Love and best wishes
Alison
