Hip Replacement Surgery VANITY

Seems like I might be looking at left hip replacement surgery in coming weeks. Has anyone had this done? If so, at what age? What were symptoms that led to the decision for the surgery? Experience with pain, hospitalization, PT, general recovery? Anything you wish you had done differently either before or after? Thank you. This is not something I ever really thought would be part of my future and am trying to prepare myself for whatever is to be expected.
