I have been to Dr 4 times......with pain on left side of middle back....thought pulled muscle a week later I had sharp pains between breasts going to jaw just sitting at computer....had blood work no heart attack said I had hiatal hernia which was stable........3 visit EKG no change since last time but pain is at a ten just below left back bone......I see Dr again tomorrow but not improved or treatment except 800 mg to reduce inflammation which caused heart burni
