Since you have hired an attorney to represent you, you should be consulting with him/her about your concerns.  Contact your attorney and discuss your question with him/her.  There may be some insurance available under your own auto coverage that can help with your medical bills (called medical payments coverage).  If your attorney is not answering your questions or is not responding to your phone calls, you may need to consider hiring a new lawyer.
