What are Rouleaux?

Most of the explanation is lost on me, but knowing what a red blood cell looks like and what it would look like if they are stacked, makes it possible for me to understand that this is not a good thing.

I thought that the explanation was excellent. I’m an RN and I love medical questions. I certainly understand that others may not appreciate all of the detail. I, though, am lost when it comes to to questions on TV. I’ve not seen TV since the Gulf War. It seems that I can’t sit still long enough and I get impatient with the ads. I’m sure I’ve missed some excellent presentations. I get my news from reading.

Any symptoms? Cold extremities?

I have no idea what the explanation is trying to explain what it’s explaining.
