Shortness of breath while lying down, has progressed over a week to intermittent chest pain and hollow feeling in chest with sob still. Ekg was fine?

Shortness of breath. There are multiple possibilities for what you describe. You should go see your doctor and be evaluated. The doctor will order what tests are indicated, if any. Be sure the doc explains what's going on to you.
That's not enough. Look for dr. Ron peters at mind and body medicine clinic and ask for multifunction cardiogram test to see if your have blood supply issues to your heart - or myocardial ischemia. http://healmindbody.com/.
