Have you ever had a hip replacement or known someone who did, and if so, how was the recovery?

I don’t need a hip replacement.

A friend is getting one today, and she is going home right after, not to rehab. She has a husband and two teenage children, and apparently the doctor said a condition of her going home and not to rehab is she has to have someone with her at all times.

She asked me to come over tomorrow, which I am going to do, to hang out with her and help her if she needs anything. Her husband will be at work which is why she needs me there. I am just wondering what I can expect as far as her ability to do things for herself. I know everyone experiences pain differently so what was very painful for one person may not be so painful for another person, but if you want to comment on your knowledge of pain levels for this recovery, please feel free.
