I was going to ask the same as Mister James. If the shortness of breath gets worse when lying down perhaps that could be mitral stenosis causing pulmonary edema which is what I had. Did they do an echo? I am so sorry you are feeling short of breath. For what it’s worth I had NO edema in my legs but I sure had edema and pulmonary hypertension in my lungs. They took a ridiculous amount of fluid of me in the hospital under lasix.
