Welcome Lisa.
I've had RSD and TOS since 83. In 98, I got a TBI, and some discs. The brain injury really cost me my life, and it's very slow to rebuild.
My story is posted elsewhere, so, I won't rewrite it.

I can tell you this.
RSD (and all chronic pain things) can be looked at like a triangle of care.

First, your Medications. Your Doctor works with you on this.

Second, your Psychology. Your mood, and how you deal with it mentally. If you are fighting depression, you need to see a psychiatrist who deals in pain management.
There is no reason that depression Must be present with Chronic pain. But, since it "Naturally" occurs, some of us need the support of a psych doctor, who understands pain, and can help you "Build a defense Strategy" to the depression and fear, which are in your head. And, after that runs it's course, you may need to visit again, occasionally, to remind you and help with your strategies.

Third, Exercise.
I see so many people who say they're fighting. Well, it IS a fight, but it's what you make of it. If you're not getting out, and walking and if the RSD or pain has stopped an active lifestyle, sitting on a sofa is going to help the disease take you down quicker!
Exercise is a MUST!
I don't want to sound harsh, for instance, here today, it's cold and rainy, I'm NOT going for a walk outside. But, when the sun shines, so too must I. I get outside and walk!
Your heartbeat must be taken higher, and all organ functions need oxygen. That means working the cardio system. If you don't, the disease will strike at you harder.

This becomes a lifelong process, for most of us. The only ones who have been cured of the disease that Im aware of, are those who Exercised through the pain, early on.

You've come to a good place Lisa!
I only arrived this week myself.
Welcome!
Speak your concerns, and ask your questions!

Best Wishes to you!
