I too have AVN bigtime! Just had my rt hip replaced June 23rd. Next I get core decompression on the lt. hip, then both shoulders replaced! I don't have anemia, but I have Ideopathic Interstitial lung Disease. I am in the final stages of recovery from my hip replacement as I type! If you email me w/ specific concerns, I'll be happy to answer! Best of luck to you! By the way, I had my surgery at Lee Memorial hospital in Ft. Myers, FL.
