I am so sorry to hear of this, what a horrendous experience and a worse testament to the medical establishment there. I have a couple of thoughts for the future:

1. keep in your purse somewhere a note saying you have PD and what you HAVE to have, maybe a wrist band or similar? That way if you cannot speak they will at least have a clue;

2. write a letter to the state board of medical examiners naming the folks who treated you so horribly, name names and specifics, and cc the director of the hospital and the ER head guy/gal. I might even include a brief description of the classic PD symptoms so they are halfway educated for the poor PWP who might land in their ER in the future;

3. take your friend who was with you for a treat, for the both of you....her, for being by your side, and you, for enduring the ordeal.
