>When you “crack” your knuckles, or any other joint, it expands the space between your bones, creating negative pressure that draws synovial fluid into the new gap. This influx of synovial fluid is what causes the popping sound and feeling when you crack a knuckle

this
all you did was the equivalent of cracking your knuckles somewhere in your upper thoracic spine
its just not common to happen due to the amount of other bone structure and muscle tissue surrounding the area

You 'cracked' your spine.

I figured out you could do it about a year ago, & I do it at least twice a day


'Cracking' any part of my body makes me feel less stiff
