Sometimes when I'm anxious, I feel like a light pressure in my upper chest (never in one specific spot, and it comes and goes). It kind of feels like a bubble. I start panicking, worried that I'm having asthma or a heart problem. But if I move around my shoulders until I hear a bone or two pop, the pressure thing is gone or at least relieved. I guess it's tight muscles in my chest from anxiety? I can never figure it out. (I went to urgent care a year ago for it, and the doctor acted like I was ridiculous and said it's "probably costochondritis.")

Can anyone relate?
