Chest pressure/discomfort for 3 days. seems to come and go. occasional sob. sometimes get kind of burpy too. also have bad anxiety. i aslo breastfeed and don't know if fullness can cause this. could this be indigestion or anxiety?

Chest pain has a wide range of causes, with life threatening (cardiac tamponade, pulmonary embolism, myocardial infarct, aortic dissection/aneurysm, esophageal rupture) to less life threatening (pneumonia, pneumothorax, indigestion, GERD, musculoskeletal pain, peptic ulcer/gastritis, anxiety attack). A clinician will need to do a full history and examination to provide you the best answer
