My workers compensation claim was made in the State of: illinois, hello all i currently have a claim for carpal tunnal in both hands. last week my supervisor had me picking up 100 lb machine parts and i hurt my back. made an injury report then went to doctor. he told me if my back still hurts he will give me further tests. well 3 days later back is still very painful. i had surgery on my back about 7 yrs ago. if this is serious can i file another work. comp. claim?
