I have had difficulty swallowing, pain behind my sternum, coughing, fatigue, lack of appetite times 3 days now. I did not think that it could be acid reflux as I have never had that problem, so I have not taken anything for it. The pain is almost constant anymore even when I breathe I can feel the discomfort. I am not suffering from shortness of breath. I have been belching a lot. Pain does not radiate to my back, left arm or jaw. Just in the center of my chest. It seemed to be a little higher last night and is a lower this evening but still there. Should I make an appointment? Go to Emergency? or what.
