Hi Reneetina and welcome to the forum.
I can't answer many of your questions because I haven't had revision surgery, only the initial one, nearly three years ago. But regarding the bone/blood question, I just wanted to say, each surgeon seems to have his/her own opinions. My own surgeon didn't want me to donate my own blood or bone from my hip, and I'm grateful for that. Taking bone from the hip can result in some pain long after surgical pain has gone (though not always.) I was given donor bone, plus my own bone from osteotomies (small chunks taken from my spine that had to be removed anyway) as well as BMP which is a man made agent which ensures faster fusion. It seems some think that donating your own blood can result in you being not quite up to par on surgery day. I suspect this to be true only if you donate within a few days of surgery, which doesn't sound like a good idea. These days, donated blood is very safe.
Good luck negotiating the forum and I hope you find a great surgeon who can help you back to a healthy life.
