Oh, a head scan; they are bad with the noise unabated right there where your hearing is, don't think you can wear headphones if you have it for your head (I got headphones when I was just doing my intestinal area but that was hard because I had to hold my breath off and on as they commanded me through the headphones). I had one for my ears/Ménière's Disease. What got me through it was thinking forward to afterward; schedule it for a time you can go to a meal afterward or some other reward and think about that. Think about what you are going to tell us about it afterwards on here

Play games with the horrid, clunking sounds; see what the limits of your being able to think are :-) like trying to think about what you are going to talk to your T about next.
