Ok, I guess it's not completely made up. Same thing, different name.

Take a line and slice off the very corner of that thing. That's what I did (..it was surprisingly easier than you might think. All you need is a mountain bike, and a mountain.)
Actually today I go to have my (hopefully) last x-ray of it done. Yay! My mobility is mostly back but there are just certain things I still have trouble with. Last week I was trying to empty a packet of sugar into my coffee. I can extend my arm, and I can rotate my arm. But extend AND rotate? Wow, that's a surprisingly complex motion. I could do it but I really had to concentrate.
Oh the joys. I don't want to break another greater tuberosity of the humerus. I can scratch that one off the list of "things I've done to myself."
