Don't know anything about X-Rays but I know this. Do what you can do. Avoid what causes trouble. Flat Bench Press for instance is brutal on the shoulders but Incline Bench Press or Parallel Bar Dips aren't but work the same muscles.
Years ago my left shoulder was so bad it hurt to the point that it would wake me up if I ever rolled over onto it in my sleep. I started light and slow. It popped by popcorn with every rep. Eventually It stopped hurting and then in time it stopped popping. Today I can do any exercise with it pain free. Oddly enough today it is much stronger than the other.
