I started by having like chest congestion symptoms which later develop to like a shortness of breath and it causes me to start having palpitations which rushed me to the ER one day and the next day i was on ECG and Electrocardiography which turns out all OK. but doctors quarry GERD which i treated with omeprozole and damperidone but now am still having issues with shortness of breath and belching especially when i eat some certain foods pls do GERD causes that?
