No, I'm not really a blonde- I'm decidedly blonde.
But I am a registered nurse- and conditions requiring a MRI are usually painful; therefore, my comment about pain and the 5/500 (as in Lortab 5/500) most of the time prescribed for moderate to severe pain- depending on your tolerance/pain levels.
Hopefully the results made him VERY happy-at least happy when he could exit the noisy contraption.
