oval shaped lump on lower rib cage

[Dar584]

I have an oval shaped lump near my left rib cage.  It is about the size of a walnut.  It does not hurt and I it is somewhat moveable.  When lying down it sits on my lower left rib cage and is very definable but when I stand it is below the rib cage and hard to feel.   Any ideas on what this could be?

Thanks for the replies.  I have to make an appointment just hate going and then finding out it is something stupid.  But I guess better safe than sorry.
