2 weeks ago I went to the emergency room with chest pain. I had a stent placed in June 2011. I also take aspirin,lipitor, lisynipril, clopidogrel and a over the counter for heart burn. I also have a cough (I have had for 2 months) a sore throat and lower back pain. (feels like I broke my tail bone) an EKG, blood test, chest xray and strep test was done. My heat doctor said it must not be my heart. I just had another chest pain this afternoon. I don't want to be a pain to my doctor. could this be severe heartburn?
