We're all hoping it's not sinister Michael. Please let us know and also, I would obtain the records from your ER visit on the 17th. You posted:
Having been there done this before, the x-rays and CT scans absolutely would have picked up lung nodules and nodes. As you've had extensive testing of your heart as well as scans of the areas now affected, I would also obtain records and images from previous x-rays and scans done in the last 6-12 or so months as they would have shown this as well. I can't imagine they would have missed your lungs being full of nodules as cancer doesn't pop up and grow overnight! If indeed those images show something, I would obtain an attorney!
