Well, I had full knowledge that my last MRI would be anywhere from 2 to 2 1/2 hours.
I was given numerous chances to get up and take a break but I chose to stay in the MRI machine for the entire time.
Was I stiff and sore? Yes. Did I know I would be stiff and sore when I made that choice? Yes. Would I do it all over again the exact same way? Yes.
I made the choice to keep going without a break because I simply didn't want to make my MRI stay any longer than I needed too. A 2 1/2 hour MRI would have been even longer had I taken a break.
But, that's just me
