Don't most police officers have a union? I don't know if they would be of any help though.
Comp Ins carrier should have sent you some information.

Your state should have WC info on the state website.

I do suggest getting a work comp atty to help you get thru the details and paperwork. Interview many before signing with one. { many are just out to get their 15% cut of a settlement without really working for you}

It's really hard with comp to try to give detailed scenarios of what will happen.
But in general some things to remember-
the Ins comp carrier is not a friend,
don't discuss claim with any co workers or employer {only basic info if required}
get copies of all letters, records and tests - keep them organized
do as your treating dr says - as far as all activities and limits- {if a major/chonic injury or big money claim they may be watching}

Much depends on the injury itself & how it came about.
- an acute accident with witnesses?
vs a repetitive or soft tissue injury that has developed over time?

as far as compensating you for care giving- most likely not unless dr states that some care is needed - but they most likely will suggest a professional if required.

But yes with RSD ongoing open medical is a good idea.
{ you will need firm proof by expert dr/drs that it was caused by the injury}
