Chest Pain

[Guest]

hi, im a young male (20) who did weightlifting until one day i feeled very bad, and stop doing the exercise, i thought it was a heart problem, that was 4 months ago, i went to doctor and did a variety of lab exams, like ekg, echocardiogram, blood, and others. i have seen three doctors and all say i dont have nothing. but i have this pain on my armpit (left), upper left chest, center part of the chest, down the the left ribs, and back.

these pains 3 months ago were a lot more intense than now, now there are like more small. they are not constant, and not alway on same location. but i wonder what could be, my physician tell me to relax, but im with the doubt. some one can help me with this trouble...

thanks
