shortness of breath
when lying down can be a symptom of congestive heart failure
. I would recommend if you feel like your are drowning, that you consult a physician because this is a serious condition. You also may have sleep apnea
. if you have leg swelling, or shortness of breath with exertion, these are also concerning symptoms. Several tests and physical exam findings, and we'll come up with a right diagnosis. This is not just a quality of life issue but a medical problem. This is probably not related to your reflux. Cheers.
