Pain between hip bone and ribs on left side.

Since yesterday I've had this muscle cramp like pain between my hip bone and ribs on my left side. It was very intense yesterday that I was crying. I couldn't get up on my own or move without the pain. It started easing up towards later that night and after that I was just uncomfortable. Today I still feel it but since I sit all day. I can feel it getting a little worse. Is this Normal? According to the women I spoke with it happens but I just want to be sure.
