PALady, I am sooo sorry this happened to you. You might want to take a hot soak in a tub before heading for bed, too. I hope you haven't hurt your back or jostled your hardware.
With bilateral hip replacements and two revisions on the left (and a rt. revision in my future), I am deathly afraid of falling and dislocating a hip. I'm in FL, so no snow here, but am really careful getting in and out of the shower, and still use a shower chair so I can sit.
Please, please be careful and take care of yourself first and foremost!
