                        I just had a cortisone shot in the hip administered at Mayo to test whether I have AVN or not.  Supposedly, only a small lesion shows up on the MRI of my left hip.  Had a kidney transplant 2 years ago, so is supposedly caused by steroids. My doctor thinks I should have a core decompression at some point. After your shot, what did you have done?
