i have this problem where if i bend my arms back and head back and chest up, i can pop my sterum. i dont know if its bad but sometiems if i dont pop it theres a cramped feeling in my chest and i can feel like pressure there like i have to pop it like a knuckle. also if i dont pop it, i noticed i cannot do some movements such as pushups. those are extremely painful with my sternum in the "unpopped" position.
recently my sternum has been popping more and more and its to the point where I can't pop it anymore and still the pressure is there.
i was wonder if any of you had this problem.
