Why do I feel movement on top of my ribs?
For a couple of months I've been feeling some weird movement on top of the ribs on my left side below my breast. At first I thought it was heart palpitations, but it seems to be separate from my pulse. It's not painful, and some days I feel it all day long and others not at all. Could it be muscle spasms or gas or could it have to do with the blood flow? It really feels like something is moving. I don't have any health problems so far, but it's really bothering me.
