If they give you prescription painkillers, make sure to poop at least once a day, hell or high water- take a laxative if you need to, but be vigilant! The good stuff will totally stop you up, and before you even notice four or five days will have gone by, and ultimately that first final “go” can be worse than anything else related to the surgery.
Try to have the house cleaned before you go in. It’s a bummer being laid up in a messy house, and so much easier to get around when you’re not having to navigate hazards too.
Get a big water bottle and a way to move it around- a carabiner or something.
Stairs up aren’t too bad, bu I’ve found that it’s very easy to lose your balance going down stairs - once the immediate pain is gone, I typically just toss both crutches into one hand, hold onto the banister with the other hand, and “hop” down the stairs instead of relying on the crutches at all. For doors if possible just push them open backwards with your butt, shuffle through, and swivel around.
Beware of slippery patches in general if there’s weather where you are, like the paint on the ground in crosswalks, and tile floors.
You can get little saddlebags for the crutches but you might find they just throw off your balance; I just used a messenger bag.
Last time i was on crutches for a long spell I started getting cabin fever, but it was so exhausting to drag myself anywhere-- a comforting outing was to go to a fairly new supermarket, one that had courtesy scooters, and just cruise around the store shopping with a friend.
Let other people spoil you! Especially at first, since later you’ll be feeling better and the novelty will wear off enough that people don’t offer as much anymore
