David got an ultrasound on his abdomen today. They’re checking his liver and spleen, because his bloodwork has been abnormal lately. (His wcb, red cell blood count, and mean platelet volume have been below normal.)

David was a real trooper through the entire thing. He chatted it up the entire time with the ultrasound technician, asking questions I’ve never even thought to ask, about sound waves, what pitch those sound waves have to be to get a picture, etc.
