I have the same exact thing the pain spreads to deifferent parts of my chest. I had the holter monitor chest,stress test, blood test, ekg's, and xray's and everything came back normal. So they said my cause is anxiety. The chest pain gets annoying. They have gave me some beta blockers to try to help with the chest pain but the only thing is that the blockers slow you down. I also been to the ER several times and everytime the found nothing. Hope this helps.
