Plastic Surgery Complications - Update (again, again..)

I think MIL might be well enough today to try to make it to the boy's football game.  She's been basically "in bed" since her lower body lift weeks and weeks ago.  I don't think I mentioned that the doctors have now diagnosed her freakish passing out episodes as "vertigo."    She's had near-passing out episodes in front of her visiting nurses and family.  They have all been freaked out by it, causing more than two trips to the hospital and PCP for check-ups.  I do not know anything about vertigo or why it came after this whole plastic surgery nightmare?  Anyone?

Update:  She came to the house for a very quick visit.  She's cannot move her head or move fast - or she's instantly dizzy.  She tried to visit with the kids, but was soon asking to go and lay down at home.  How horrible!
