S.B.
I had a thyroid biopsy before and the way that I was able to stay perfectly still was to look at the ceiling and trace imaginary lines from one dot on the ceiling to the next during the whole time. I only "traced" the area above me, not around the whole room. That way I only moved my eyes tracing the dots, but I had to concentrate to do it so I wasn't paying much attention to the biopsy procedure. If the ceiling doesn't have dots (or crevices) you can "trace", then "outline" in your head the ceiling time, slowly, so you stay on the "line". My hope that helps! Good luck with your test.
