For the past 6 months I have these dull aches in my chest, mostly on my left side. I am obviously not having a heart attack because i am still alive, but they are very alarming. My dr seems to think its stress related, and has not done any other tests. I am 25 years old...drink occassionally, just quit smoking a month ago...it feels like i need to stretch that side or something. very strange...anyone else get this???
