physical therapy helped me to gain some movement in my hand and elbow and shoulder but not so much in my wrist. but it did help the other parts of my rsd site and if you want to you can ask your dr to write you a script for pt. the only problem i had with pt is that at the end of each session they put ice on my wrist. i started having more pain in my wrist after a few months of icing. i didn't know at the time that ice can further damage rsd nerves but now after research i found out it not good to use ice on rsd parts. other then that i think pt is helpful. i hope you start to feel better and gain more movement soon.
