I just spoke with our cousin Marian, aka mrua7, who is currently in the ER.  She's going to be fine, so says the doctor, but he wants to keep her in the hospital overnight to observe.  Some symptoms became alarming enough to her that she went in on her own, with one of her cousins (the flesh and blood kind) doing the driving, and for moral support.
She says she feels much better, but a little tingling in her left hand and some loss of control made her concerned about a possible stroke.  Happily she is out of any danger and all of the feeling is back where it belongs.
Let's keep expectations for a good report, with prayers and kind thoughts going her way.
