Does anyone know anything about Workers' Comp Laws in Louisiana?

I was hurt on the job and now 3 months later I'm not getting any better. The insurance company's nurse met with my doctor and the doctor stated to her (and she in turn re-stated it in a confirmation letter)that my injury was work related. Not a week after this meeting the insurance company dropped my claim saying that it isn't work related. They just stopped sending my paycheck and after a week without it I called to find out what was up and they said they weren't covering me anymore. Teh didn't even bother to tell me. Now I'm trying to contact my boss to find out where I stand or if I have a job or not and he doesn't return my inquiries so I'm stuck in limbo. I'm 34 and have a wife and 3 kids that depend on me and now I have no income, my leg can't get fixed and I can't afford a lawyer. How do I fight back???
