So just recently I've noticed my sternum will pop or crack occasionally if I turn my chest a bit, or move my shoulders down and inward. It's just like cracking your knuckles or back, feels and sounds the same.
I've never really heard of this before and I kinda figured the rib cage was a good ol' solid piece, but perhaps I am wrong?
It does not hurt or anything, and actually feels kind of pleasant when I do pop it, which is a couple of times a day, especially if I sit still for extended amounts of time but I notice it, and am just curious...
Anything to be worried about? Anyone else seen this happen before?
