I get chest pain all the time. I think it's a cause of my anxiety rather than a result, at least as far as I can tell. I've also been checked out by a cardiologist and told that I'm fine.
I have different kinds of pains - sometimes it might just be heartburn, sometimes it's tight across the top of my chest and back, which I think might be due to poor posture. The very worst pain I get (which I've been getting off and on for many many years) starts in my lower left ribs, and shoots upwards, sometimes into my shoulders and neck, sometimes down my left arm. It's a stinging kind of pain, almost like a charley horse but in my chest. Maybe it's a spasm in the intercostal muscles? I don't know what causes it. Luckily I don't get these very often.
I probably have some kind of chest pain (usually very brief) at least once a day, but I'm probably more sensitive and just looking for it more than your average person.
I don't know if that helps you at all, but at least it's an example of someone who often has chest pain that doesn't seem to be heart-related.
