mylegrams procedure ?

I had an x stop spacer put in my back in January, and 2 weeks later I started have leg pain terribly. So I went to a different doctor and said it is more likely to be a pinched nerve and nothing to do with a knee problem, so he suggested mylegram, but I remember how painful those are and was wondering do you think if I ask the doctor to put me in the hospital the night before to relax better and keep me overnight after the procedure they would? I know you have to lay flat for at least 4 hours.
