I have asthma and sinusitis (recently exacerbated), am about 40 pounds overweight, and am occasionally (1-2X per week) aware of heartburn (e.g. burping acid into throat). For the last month or so I've had increasing dull chest pain on the right side (next to my breastbone), sometimes extending up to my jaw, sometimes to my upper arm, shoulder and back. I have no cardiac symptoms (no hypertension, palpitations), and the pain occurs without apparent immediate cause (not exercise-induced). My regular physician says he doesn't think it's cardiac, since I have none of the usual risk factors or indications.
Could this be GERD pain?
