Glad she's outa the hospital, Brad. They are dangerous place - I should know, I haunt one myself!
Did they give her any other painkillers to take at home? She ain't gonna want to move much when the narcotics wear off, but unless the doc said she's not to move she needs to. Get those joints moving or they'll all sieze up again and you'lll spend the rest of your life feeding her mush in bed.
So it's in your own best interest to be tough and make her move a bit. Hurts, but it's necessary.
She got any physical therapy booked yet?
Cheers
Mick
