Welcome Jenn,

I am a fan of warm water therapy pools because I spend a good part of the year freezing cold, and it helps me exercise my arms and shoulder a bit in comfort. But I see you live in Hawaii so perhaps that doesn't apply to you!!

Try to find the very best RSD doc that you can. A good physical therapist can be helpful also. They are really hard to come by when you have RSD.
The RSDSA has a database of docs, check it out. also check to see if there is a support group in your area, I learned an enormous amount about what local resources were available just by talking to others RSDers in RI.

There are some good support groups on FB, too.

We are all here for you. Xoxo. Sandy
