I have similiar symptoms and have been diagnosed with acid reflux. I have a pain in my left side under my arm and in my left breast. The pain is also in the center of my chest under my rib cage, kinda where your bra is.
Lately I have noticed a constant cough as well but really didn't think anything of it. I'm waiting on the dr. to call me back as I am typing this.
I'm tired iof being tired all of the time and feeling like I'm 78 when I'm only 38.
Sorry, I don't have any answers for you. Didn't mean to vent in your thread.
