I may try HBOT now too. For me the therapy mentally that I liked the best is biofeedback. I have a lot of anxiety and really was amazed and how I could calm myself down at times. I have down CBT many times before rsd. At the pain clinic we had group and individual therapy as well. I recently went back to a pscyh after a break for awhile due to the pain and how it was mentally effecting me. I am so glad I did because really my anxiety has been helped and mentally I don't feel as crazed. It has not helped with my sleep and I still have a lot of work mentally and physically but one step at a time. I am not going to do this but my pain doc now who does reg treatments told me to look into acupuncture. I am not like I said going to do it but they told me that they would not have to put needles in or even near the rsd areas so just fyi to people. Hang in there
