OK, so my doc recommended to have an MRI done of my lumbar area to see what's wrong with my back. I show up today at the Imaging Center and they take me inside this room with a huuuuge machine in the middle of it. I mean I've seen MRI machinery before but this was a behemoth! The doc explained to me what's going to happen and he then asked if I'm claustrophobic. I say 'No, I don't think so'... Well, once he slid me in the middle of that behemoth I felt like being inside a coffin! The tube I went into almost touched my face and my entire body was pretty much confined like that. Then the doc says "I'll have you lay motionless for 30 minutes" and at that point I say to him "That's it doc, I can't deal with this!" So he pulls me out and I left, halfd embarassed that I couldn't deal with the enclosure. But hey, I found out more than half of the people experiencing for the first time an enclosed MRI react the same. So I'm going to request an open MRI. And I can live with myself being half way claustrophobic.
