pop goes the... thoracic vertebrae?

[agnor]

There's a spot in my thoracic spine that I can usually pop if I stretch in a certain way. It's likely the same place pointed out to me by the chiropractor my stepmother used to take me to.

Here lately it's felt like a kink in my back that needs popped. But I can't pop it. Sort of like an itch I can't scratch, only this one aches instead of itches.
