I'm a bit confused.
Was the injury work related?
Did you file a work comp claim?

Is that why the drs have down graded the diagnosis?

Or are these your own drs?

Oh , I took a look at your other posts, I thought your name sounded familiar.. I replied to you one some of the earlier threads.

I guess my next question is do you have a good work comp atty?
A good one will hopefully point you in the right direction in the best steps to take now.
{ do internet searches to find good ones & interview a few before signing }

I think you need some professional legal help to get back on track, if it is a work injury you really should go forward with that system.
Have you visited our Workers Comp forum?

If it is the WC drs /or employer telling you to go on state disability - they may be hoping you won't follow thru on the wc injury claim.
