question: I have been having a bad pain just under the edge of my middle left rib cage. It is slightly burning sensation that seems worse when I lay down. I also seem to have a lot of inner twitching for lack of a better term, on the right side just under my rib cage. I have no history of reflux, andhave only had heartburn during pregnancy. I am currently without insurance and would hate to go to the ER for gas or something relatively normal.
