I had the same experience with my Mum 3 months ago! She lives in England and I bugged the hell out of her Doc`s trying to find out what they were looking for. Of course I was convinced it was some sort of cancer, it was stones! I never heard of stones concerning the liver.
Hopefully you will get the same news, in the meantime come down from the ceiling, its uncomfortable up there.
Sending lots of positive vibes your way.
Take Care
