Re: Pain when laying on left side: IBS?
IBS can cause splenic-flexure syndrome.
This sounds scary, but its TOTALLY benign. It's just that your bowel has a rather sharp kink (the splenic flexure) and when gas moves round here it can cause pain - most often quite severe.
This is nothing to worry about, especially as its relieved with a bowel movement.
I've had what you describe and its nothing!!!
Good luck
