Reply to HealthGuru aka Emily's Post: actually these have been ruled out. the pain starts in the mid back, feeling like someone has stuck a knife between the shoulder blades, then travels to the front, and then up into the jaw line. there is not a burning sensation, just a lot of pain that can be, but not always is, accompanied with sweats, nausea,the feeling of rapid heart beats, light headiness(dizzy), and in some cases, fainting. It can come on any time of day or night, but if you are experiencing a stressful day, the symptoms are worse but they are not or seem not to be brought on by stress. We have been told everything from gerd, to kidney stones, to gallstones, to hernia, but no one seems to feel that the doctors take them seriously. Our mother died of a heart attack, her mother of a stroke, a sister of an anurism(?)that occured in the stomach, my birth father had similar complaints and had a stroke/heartattack combination that killed him. We know that its not from the ears, no ringing or pain there, the pain travels up into the jaw line.
