If I seek new council, would I owe this attorney any money?

I got into a car accident on the job delivering parts for continental car. I got rear ended. Injuries were two 4-6 mm herniated discs in my cervical spine and my lumbar spine. This happened in August of last year. I finished physical therapy about 6 months ago. I am still in pain. Bills total over $30,000. Finally, I got an offer from worker's compensation for 3% total loss of use. Also, I got in an offer from the personal injury insurance of the driver. Lawyer won’t tell me via email what it is though because he said he wants to go back to worker's compensation insurance first, and then have me come into office to discuss options and sign paperwork. Problem is that the WC adjustor hasn’t responded to my attorney in almost 2 months. I feel like something fishy is going on. I am not satisfied with the tenacity my attorney is showing. I understand that the more I get, the more he gets, but it doesn't seem like he cares that much. He has allegedly filed a motion for trial already.
