I second getting a Good wc atty on your side!
Then your atty should have a list of good drs that can help with the wc claim and proving you got rsd from the broken ankle injury.
RSD & the cause of it is a difficult claim to prove, so getting a dr/drs that knows a lot about it and can track your pain & symptoms, and give good treatment for it is a good thing.
It helps if they also has some experience on claims of this sort.

Have you had any xray/MRI scans just to be sure nothing else is the cause of the pain & sx?

On member did turn out to have a pinched nerve for years, thinking it was RSD and a friend talked her into seeing a good chiropractor - who did an adjustment of her ankle?? {I think that was her area of sx}.
And the pinched nerve was the problem the whole time!

Have you had any tests or treatments, other than meds?

Look thru our WC forum also for claims and tips info.
