What can I do for the time I missed work for this injury?

I am sorry you are facing difficult times and a painful injury. It is not clear that there is anything that you can do, but you would get better advice in a consultation with an attorney, during which the facts can be better covered. Among other considerations, if this accident happened during the course of your employment, then you may have a workers' compensation claim regardless of fault. Also, if you have any short-term disability coverage, through your employment or otherwise, you should look into it. If there is not any basis for those claims, then it may be that anything beyond the auto coverage for medical bills will have to go through your health insurance or be paid out of pocket. If this causes substantial financial hardship, bankruptcy may be a consideration.
