My affected area is also in my good hand/arm. I've also had surgeries on my hand that may or may not have made it even worse.
Finding the right doctor(s) will be key in understanding exactly what you're dealing with. Having an ortho, a doctor for pain management, neuro, physical therapist and whatever else you can muster together to make a team working for you, that's when you have the highest chance of stopping or slowing down rsd. Thats what I try to do.
As a result, I feel im getting the right medications, treatments and therapies I feel will help me the best with what situation I am in personally.
Everybodys situation is different but early treatment is a big plus. I wish you luck, I also have children and am fairly new to this so I feel for you.
Good luck and best wishes.
