7:02 pm After spending all day at the hospital, and assuming she would be admitted, Susan called a couple of hours ago to tell me that she was going to be discharged (I was on my way to Chapel Hill with an overnight bag assuming she would be admitted). The good news is that she does not have a pulmonary embolism (a blood clot in her lung). She does appear to have "pleuritic pain" or pleurisy, which is an inflammation of the lining around the lungs. That would explain the pain with coughing and with breathing. I'm sure she has way more information that I have (I only know what she told me on the phone and what I've been able to glean from the internet). It sounds as if the plan for right now is to send her home with some heavy duty Motrin and for her to follow up with another doctor some time soon. Thanks to everyone for their prayers. It's been a weird, weird day, as you might imagine.
