chest aches/pains for 2 yrs

[eddy1608]

hey as you can see ive had this for 2 yrs now and in that time i ve had 3 ekgs and blood tests and lots of gp and hospital visits thinking its my heart. i am 25 and no previous or family history of heart problems and i am always told i am fine. along with the chest aches and pain my upper back is awful aswell and when i tense my upper back and chest the pain gets worse and when i un tense its not as bad so that sounds muscular doesnt it? also my gp referred me to physio to correct my posture which they said wont be healping me at all. if anyone has any experience with this or tips how to ease the chest muscles i am all ears lol
cheers guys

Could be a lot of things I guess. I'm in a similar boat to you.
Avoid caffiene, improve core strength and posture, relax more? What have you already tried?
