A Huge problem with litigation, is the 'But For' argument.
As in, But for if you had been diagnosed timely, would you have been cured?
Highly doubtful.
I waited about 7 years for a dx.
I'm fairly certain to myself, that if I was DX'd the day after the accident, I would NOT have been cured. Then the spread, is after time goes on, reasonable to expect.
The best thing is to concentrate on learning to take good care of yourself, and your rsd.
Triangle of Care;
Keep Moving, Exercise.
Take the Proper Meds, (be sure you've got the best doctor you can find)
And, Your Head! This disease is a Big psych killer! Get some psych help when you feel you need it, it's a strength, not a weakness!

I wish you the best!
