I was wondering if someone could help me out. I have had several back injuries and now as a result of all my injuries the doctors are saying I won't be able to do any kind of work at all. One doctor said I could work a maximum of four hours a day. Can you tell me what is the difference, I thought this would be considered permanent total disability. Is there a chance they might rate based on permanent partial disability and what is the difference? Is it considered permanent total if you can't do any work at all?
