Hi,
I've had chest pains too, for 2 years now.. Quite sure it's stress induced as it follows my emotional and outside-stress situation. It started w pain between th eshoulderblades 6-7 years ago, since 2 yrs my sternum gets very sore and the pain spreads to intercoastal muscles and collarbones etc. Sometimes i get inflammations due to muscles getting pulled or pulling ribs out of place.

I went to a kinesologist friday, first time, and was quite impressed about what she did - i had to think about the thing which worries me and she'd do some muscle tests at the same time, then she'd work on some spots on my body, i cried, and when she did the tests again it was better and i didn't feel as worried about that thing. i'm going back there monday, feeling very curious and even hopeful that it might help. I guess it will never go away until i resolve some confidence-etc-issues i have and find peace with myself.

I'm not sure if what you experience is similar -you should defentiely go to the doc like the others have said. Feel free to contact me if you like
