I am female, 20 years old. Recently, I often have a feeling of heaviness in my chest when lying on my back, but changing positions is okay and sometimes I have indigestion (a feeling of choking in the neck). The doctor asked me to ask if my chest is heavy when I lie on my back, what is indigestion? I thank you doctor.

I have indigestion, or belching. Initially, during the day, I did not have difficulty breathing, at night I could not sleep at night, now it is more frequent. Day and night belching, shortness of breath, hot right upper back. So the doctor asked me to eat indigestion with difficulty breathing, what are the signs of disease? Thank you doctor.
