IVP dye!! Told the nurse in the radiology dept I didnt feel quite so well. Her response was it will subside in just a moment and walked away. Needless to say I got the major "hotflash" of my life, vomited a huge amount of bile only, then out I went. Woke up intubated, on the vent, ng tube, f/c the works.
Second instance was with knee surgery in which recieved Morphine post op - my arm was itching slightly but they went ahead and gave me a second dose. Well you can get the story from there on lol, I'm allergic to morphine!
