Upper mid back pain after sleeping

Okay, so for a month and a half or so I've been having stabbing pain between my shoulder blades every morning. On a scale where 0 is no pain and 10 is throwing up and losing bowel control from the pain, this was about an 8. Neither my LMT nor my family physician had any idea what it could be, so I promptly googled to see about possible causes and found several very long threads worth of people going "oh my god, you too?! yeah, my doctors don't know what the hell it is either!" which was, needless to say, a bit depressing. It wasn't acting like a slipped disc or bone spur at all, no tenderness on the spine anywhere, and not like a pinched nerve either; we were all stumped. And, in my case, in increasingly intense pain.

Having spent a solid two weeks sleuthing through physiology with my LMT, I can report at least one cause of this kind of pain: my ribs were misaligned and locked up, and referring the pain up related back muscles. Causes and treatment reported below, for the benefit of posterity and the next poor sucker wondering why they're in agonizing upper back pain after lying still for several hours.
