Hey- Not sure if you will get this. If that pain comes back on your right rib, have them do an ultrasound on your gallbladder. It sounds alot like this "mystery" pain I had
If its the worse pain you have ever felt, like you are going to die and it comes all of the sudden and eventually lets up within an hr it sounds like gall-stones.
I had them 3 weeks PP with DD and it took the dr's including the ER drs 3 weeks to figure it out, well I figured it out and told them haha. But I had like 8 attacks and they are the worse.
Just a thought if the mystery pain comes back.
