I m feeling a pinching and tugging pain inside my abdomen cavity. sometimes it is up under the rib cage, but the pain moves. I have a gerd diagnosis, a hiatal hernia diagnosis and a possibly falling bladder...is that a prolapsed bladder?? I m not sure if that is the correct diagnosis. nagging feeling, not constant, but becoming more frequent over the last three months. I m wondering if this pain is prompted probably by one of the other issues I m having.
