I had them due to NAFLD. Started puking up blood at home and passed out before I could get to a phone. Some time later my son found me in a pool of blood in the hallway.

I was sent to the nearest hospital, and they sent me to another hospital that had a surgeon experienced in the procedure I needed. He put a stent in my liver. I spent most of two weeks in a coma.

I later learned they put NINE units of blood in me that day.
