I went into the emergency room with pain on the left side of my neck, also left arm pain. I had bypass heart surgery eight years ago. I have a defibilaor. I was admitted and became sicker. I take several meds per day, I had a list of all my meds with me. I was given Percocet and became totally out of my mind. I had to be restrained on several occasions. I had a neck scan, brain scan, ultra sound and an Egg. All results showed nothing, normal. Can you tell me what caused my abnormal behavior? I was even t a new prescription. I left with the same meds that I was taking when I went in. I need to know what was done to me? Was I given meds that I shouldn t been given.
