I have started reading on the recovery page about how important walking is. Walking is super hard for me when I do much more than walk around the house.
Don't get all hung up on walking. Just walking around the house is all you need to do for the first month or so. Even after that, you just increase the amount of walking gradually, as your hips allow.
In our recovery guidelines, we give everyone this "big tip":
BIG TIP: Hips actually don't need any exercise to get better. They do a pretty good job of it all on their own if given half a chance. Trouble is, people don't give them a chance and end up with all sorts of aches and pains and sore spots. All they need is the best therapy which is walking and even then not to excess.
Another helpful thing to remember is this:
a. If it hurts, don't do it and don't allow anyone - especially a physical therapist - to do it to you
b. If your leg swells more or gets stiffer in the 24 hours after doing it, don't do it again.
