I am a women 57 years old, 5'6', weight 130 ,father died of diabetes ,cardial vascular disease age 54.I have been having mild stabbing pain in my left chast area. I have had EKG ,ECG,blood work ,chest xray and stress test. All came back normal. For no apparent reason I recently experienced pain that started between my should blades in my back, crushing pain radiated to the center of my chest up my jaw,my whole upper body . Lasted for about 3 min,took an 325 mg asprin,after asprin it took about 2-3 min to ease up. Could this have been a heart attack?
