Thread: Midde of check bone cracking, common?

About for the last year, middle of my chest bone (not sure what it's called, located between my 2 pecs and runs down the middle), has this cracking sound and when I'm straightening my back, I hear this crack.

And it is espically noticeable when I'm benching, sometimes it actually hurts.

so, I saw a my physician and he said it was common for people that lifted weights....got some x-rays and he said it was fine...but just recently, I got a cold and after a heavy cought, it seems to be hurting rather than the usual cracking when I'm straightening my back.

Anyone else have this, or know what it is? What exactly is the bone called anyways. I'm affraid it might be worse, like maybe lung cancer or something because once in a while, I can't get a full capacitiy of through my lungs...but not really shortness of breath because once i start excercising, it's fine. No family history of lung cancer. and I don't smoke.

One more thing, I got a neck injury 3 years ago from sparring BJJ and went to the chiropractor..noticed that when I stretch my neck to the right, I get the same pain at that bone.

thanks, i hope one of you guys knows what this is because I'd love to get back to lifting

if it hurts, get it checked out bro.
onlyu thing that cracks for me is my back.
