Worker's comp legal fees are limited in your state, and must be approved by the judge. Payment is primarily based on "money moving", or actual wage benefits, and for the most part a lawyer doesn't receive additional compensation for helping you obtain medical care. If you don't want to pay your lawyer, you can proceed without a lawyer - but as you can see, when you represent yourself and fumble the ball, you can end up in a very bad situation. If no lawyer will take your case, odds are you don't have much of a case.
No, you cannot sue the judge. If you don't like a judge's decision, you can appeal. Any lawsuit you file against the judge based upon an adverse decision or his not working on your preferred schedule will be quickly dismissed, perhaps also with a determination that it is frivolous and that you should pay the other side's legal fees.
