Tara, that is exactly how it happened, but thankfully I didn't break it. I will have to be more careful when I get up now.
Katie, I do think I pulled something. It is still tender, all the way up to my shoulder.
Bonus: May and I slept in the recliner last night because she was having some sort of issue. I can't tell yet if it helped or hindered.
ETA: I feel really freaking old.
