I don't really mind medical procedures like that. The time I got punched at Elephant Butte Lake and got stitches at the emergency room I went into a deeply relaxed state that scared the nurse because she thought I'd fallen asleep. Even the noise of an MRI machine is not that startling if you know it is coming.
Indeed. I have a brain tumor (not cancerous and controlled by medication) and for a few years after diagnosis I had to get MRI's every few months for the first year, then one every year for a few years. It was a bit nerve wracking the first couple times but now I can fall asleep in those machines lol.
