So here's the view through the back of my skull (mirror image, anyway). You can see my two fake teeth glowing brightly in this X-Ray. This image was taken as a safety precaution prior to my shoulder-pain-diagnostic MRI, as I noted that there was a slight chance I had a metal particle embedded in my eye. (I was pretty sure my contact lens saved me from the metal particle years ago, but I wouldn't want to find out the hard way, by having the large magnet pull a ferromagnetic particle out of my eyeball!)

Anyway, the MRI showed that I apparently have a "moderately" torn rotator cuff and a damaged labrum. I just got these results a few hourse ago, and am debating the urgency of surgery.... We shall see!
