Ok I'm a regular anxiety sufferer and take meds, yesterday I woke up with a really sore left breast bone, right on top of my heart!!!! I began panicking and had a mild heart attack! I rushed to the ER, the doctor examined me, BP fine, pulse fine, listened to my heart, fine!! He said I had a case of inflammation in my rib cage due to my asthma & sent me home with ibuprofen .... I can't shake the feeling of impending doom, as if the doctor didn't catch something!!!!
