I had acid reflux followed by a feeling that I had lost my breath and was unable to breath for a few seconds. It seemed like acid went up my throat, nose and mouth and when it did it swelled up my tissue and I was coughing and struggling to breath. Now I burp a lot and my chest burns off and on! I know I get heartburn easily, but this is a new symptom. Has anyone else had this happen to them? Or am i alone. I have an appt with a gastrointerologist next month, but in the mean time this new sympton is bothersome. Any help?
