But, with that said, has anyone experienced like a tight or sore sternum that actually "pops" (like popping a joint, or a knuckle) when you stretch your arms back or out? I only ask because when I googled cracking my sternum, I ended up on a bodybuilding.com forum that described something very similar and a chiro described it as a condition with a name. I have no cough or other symptoms and it feels great when I pop it. But sometimes it will get sore/tight or hurt if I cough, and it's immediately relieved if I stretch. Weird, no? I figured someone else had experienced it too. And yeah, you can hear/feel it do a little pop.
