I filed and received WC benefits 10 years ago. I recently reaggravated the same injury at work during a fire drill. I filed a claim with the new employer, but i think i need to close this one and reopen the old case. Is that right and how do I close the new case that I have already requested a hearing for since my most recent employer denied my benefits. I am no longer with that employer as they have terminated me for not being able to work.
