Patient: Whenever I lay down I feel an odd sensation on the upper left side of my stomach. A little bit under the top bone on the upper left side of my belly, it feels like a button or snapple bottle cap when I push down with my finger tips. I push down and when I release, I feel a little “jump” in the same area. Almost like a button. It also feels tight around the left side of my belly as opposed to the right side.
