Tom... maybe you should call the Administration office where they said she'd stay more than 48 hours and ask why they went from keeping her a couple days to a month or more to releasing her... I mean for a diagnosis on how long she'd need care to being released... it sounds to me like something might have happened and it might be best to get that cleared up first.

Nothing wrong with asking so you know what direction to go now.. from that last visit.
I mean when I've been released due to something happening, they always give me follow up paperwork and who to go see next.

Hope it gets worked out!
