Was the abdominal pain you experienced right under your rib cage? I have been having dull pain under both rib cages, but more so on the right then the left. I actually think that is what caused my anxiety to skyrocket. I've convinced myself that it is my liver and I'm probably dying of some kind of cancer that has traveled there. I go in for my annual doctor visit next week so I guess I'll find out. I'm just hoping it is caused from the mirena and not something more serious. I've read stories from a few other ladies out there with similar dull pains, but I'm not sure if there is a connection.
