I feel a sort of "awareness" of the centre of my chest which seems to spread out to both sides of my ribs like a kind of white butterfly. I first noticed this when I started taking citalopram. Back in those dark days my anxiety seemed to "shift" inside my chest like it was a living animal warning me that it was still there and still in control.

These days I'm in charge most of the time and the feeling that I have an "animal" living inside me is long gone. I was diagnosed with a possible stomach ulcer which would explain some of the symptoms.

I think at the end of the day, chest sensations are just one of the many weird symptoms of anxiety. It's where anxiety can live.
