Do you still have you gallbladder? That can cause a lot of different pains around the rib and abdomen area. The hug, I think is the muscles in between the ribs, it mainly on me feels like the ribs are being crushed. But it does move around sometimes.

I'm sorry, I don't have the answer. But I know it is very painful for you. I'm sorry you having this trouble. I'll pray for you...
