Well, here I am again-been a lomg time since I posted any thing. After all my scans, echo, pet scan & most recently, cardio catherization (2nd time) my DR. informs me that there are no obstructions, has to be a pulmonary thing. Pulmonalgalist says its a heart thing. Back to nowhere. Hope I don't have to go thru anymore hailers, etc. Cancer Dr. has a CT scan for 7/1/19 to monitor lymph nodes. Pet scan last year showed growth on lung. Have had that for over 2 year & it's not growing. I continue to be bored silly.
