Sometimes I wonder?

Ok so yesterday I had to go get a MRI for my stupid on going back problems. Well the lady tells me to lay on the table and to hold really still. She says that this test is going to take about 25 minutes. She hands me some headphones so that I can listen to the radio and a squeeze thing that is hooked up to a bell because the test is really loud and that would alert her if I needed something because if I yelled she would not be able to hear me. So starting off things are going ok. No big deal. I am laying there listening to the radio and then I feel the urge to scratch an itch. Now how is it that your body knows exactly when you can not move and then insists on making a million things itch all at once. So I am laying there trying to ignore this unscratchable itch, thinking to myself "you can overcome this, just ignore it". So things are going pretty well. I am ignoring this miserable itch when I feel the desperate urge to cough. Now let me back up and say that while on vacation I developed a kind of nasty cough. So this would not be a little clear your throat cough, it is going to be one of those body shaking hold on to something coughs. So now I am trying to lay perfectly still, ignore this stupid itch and trying to think of any way to avoid letting this hugh cough out. So I thought maybe if I ring the bell the lady can pause the test for a minute so I can get this cough out of the way and then we can continue. (I do not want to mess this test up because it is going on 2 months of bad tests trying to figure out exactly what is wrong) So I go to ring the bell, but because I had been thinking so much about my itch and cough I had not realized that while laying in this tight coffin like machine both my arms and hands had fallen completely asleep. Ringing the bell was not really an option. I could not really even tell if I was still holding the bell in my hand. I thought well this is just great. So finally the cough got the better of me and I let it out. Of course I moved which means when I got to my doctors appointment on Wednesday he will probably tell me that the test did not come out and that I have to do it again. LOL.. Sometimes I think that my body just likes to play tricks on me like this just to have a good laugh at my expense.
PS. As soon as the test was over and I could move, that stupid itch went away. See what I mean about my body playing tricks on me. Oh well it could have been worse!
