My first step would be to consult with an attorney. Don't be fooled that this "consent" form allows a doctor to perform shoddy work and then hide behind it by saying you said it was ok. A consent form WILL NOT excuse a doctor from malpractice or gross negligence. I don't know all of your details, nor have I seen your condition first hand, but if they really butchered you up that bad, my guess is that you probably have a case...consent form or not. Most of these things get settled out of court anyway, but they won't even acknowledge you until they see that legal action is imminent.
