physiatry anyone?

This afternoon I'll be seeing a physiatrist to evaluate the course of treatment for my neck. I'm so curious as to how this is a different evaluation than those I've had with Gary PT; and if there will be any new (fun) ways to help... I've also been wondering how long the statute of limitations is on a car accident. If all of this stems from a 17-year-old car accident, should it be a no-fault case? It was treated as such all those years ago. Who does one ask about these things?
