Unfortunately I had an MRI scan today. They fixed my head with this hard plastic "cage" after I've put on the prepared headphones. The headphones docked on the "cage". First I've only heard loud noises, but after a while the whole machine started to knock. My head was of course between the headphones and absorbed all these knocking movements(just like someone knocks on your head). I got out of the machine and felt absolutely dizzy.

All persons inside he room knew that i have a concussion. I really wonder why no one was able to think about the effects on my head.
