Hello,
I have suffered from a very strange soft bulge about the size of an egg that only comes out from behind my ribcage when I bend down a certain way, for about five years. It doesn't do it often - about every two weeks but feels like an alien is moving around, and takes my breath away with the sharp pain. I now have a constant dull pain around that area. I have seen two different doctors about it, but they just think I'm making it up and don't know what it is. Any ideas? I can't sit down for longer than about an hour without it starting to hurt.
