Update: OS performed revision surgery about 28 hours ago. The cup was loose, but he ended up replacing all of the prosthetic pieces. Recovery this time around has been much harder, more severe pain, I've needed a lot more pain meds. Reduced mobility, it hurts a whole lot more to move. BUT even though the leg feels heavy I can put weight on it! So true recovery can happen.
I found out that the therapist at the hospital was responsible for asking the PA to take more X-rays before I was discharged. Thank God for both of the therapists - they are the ones that knew something was wrong and really helped me.
Surgeon has held back some information too. One of the head nurse's read his notes to us and showed us X-rays, and apparently there was a hematoma somewhere in there. I am guessing that is why he replaced everything - because hematomas can lead to infection. Am I right about that?
Anyway, after sleeping nonstop for the last 24 hours I am finally feeling a lot better! Appetite is back, I'm not so dehydrated and I am getting stronger and am able to move better. Recovery!
