Should I sign a blank phi release form for my lawyer

I think you should discuss this with your lawyer. If you do not trust your lawyer to obtain your health information, then you should consider consulting another attorney.   Most lawsuits require that personal health information be sent to the other party and thus, your attorney will likely want to get that information so as to review it ahead of time to ensure there is nothing confidential or protected that they should refrain from exposing to the other side.   Your attorney is simply that - your attorney - and you should communicate your concerns with him or her and/or ask exactly what information will be obtained with the form.  Best of luck.
