That didn't go well......

Had an MRI scheduled for today....more like 2 of them, my shoulder and lower back. Scheduled the larger machine. Explained to the techs that I was in a lot of pain today, sciatic pain down both legs...to the point that I could feel the tops of my thighs twinning and make my calves hurt. Ear plugs in, headphones playing Ozzy, in I went. Did my shoulder first, was a very long 25 minutes. Things were numb. They pulled me out of the machine to take the face mask off and to tell me that they needed me to reposition myself. Explained to them that I have a very hard time laying in any one position for that long. Repositioned myself and in I went...and I freaked out. Hit the panic button...Don't know what actually made me lose it, if it was the incredible amount of pain I was in...if it was a bit of claustrophobia setting in...perhaps both. But what I really wanted to have imagery done on didn't frigging happen. Tech told me that I can reschedule for when the day shift is there, they will be able to lightly sedate me. I don't know if that will be enough...
