I don't know how to address your other issues as you stated them, honestly.
Sorry.
Try this site for some legal help - I did, and got immediate email answers to my questions pertaining to Work comp, and SSDI; including one lawyer spending free time finding names of local lawyers for me to check on and talk to .
Avvo.com
Was very helpful .
I recommended the Work Comp avenue, due to them having the contigency avenue, and no expense to you initially, and your out of pocket expenses are after the fact - if you have not passed any time limitations.
Good Luck, Best Wishes ...........
