Was this an on-the-job injury? This is the workers' compensation forum. If you were not working at the time of the accident, or maybe on the way to or from work, you might want to post this at the personal injury or automobile accident forums.
Tricky. First you need get a lawyer on board to help you with this denied claim. A lawyer will take a percentage of what he or she gets for you, so at this point you have nothing to lose. I would focus more on getting the claim in order at this point. As far as a job search, it never hurts. But you are going to need to do this under the guidance of somebody who knows how to talk you through it. Call a Board Certified Workers' Comp Specialist in your area to help you with your case.

I would be very careful. Question include how old are you, how much were you making, are you back at work, any restrictions, future medical care?
