I have been struggling with chest pain for 7 months now. I have asthma and have been through many tests including EKG, echo, blood gas, stress test, and most recently colonoscopy and endoscopy. My condition seems to worsen everyday, but nothing is showing up on these tests. I have an appointment with pulmonary doc on the 2nd. Just really concerned and it seems like I can t get any help at the ER.
