I am not sure if your question pertains to a personal injury that you received or to the fact that you were driving under the influence.
Your best bet is to contact a criminal defense attorney, so that s/he can find out what is going on and straighten out the issues. Do not wait to get arrested.

Do not wait to get arrested. You need to go down to the court house and ask for the matter to be set for a hearing. You should consult a criminal attorney and hire one if you can afford it. Otherwise - the court may appoint a public defender. You need to clear up the warrant - otherwise - some routine traffic stop could turn into a messy arrest and cost you a great deal more in time and money.
