Sometimes at night I get odd sensations in my chest as well. One night I had a painful tearing sensation on the my left side. Got my attention. I got out bed and walk around and in a few minutes it went away. I think sometimes our head plays games because we are ultra focused on our conditions. I was diagnosed at 4.2cm back in 2009. I am now at 4.8. Have just been living my life not thinking about it.
