I've had the same problem off and on since I was in high school. I've been poked, probed and tested, all of which showed all the horrible things it wasn't (thank God) but not what it was. The meds the doctor put me on help sometimes.

I've sort of learned to live with it some days, today having been one of them. And right now I'm not any any real stress I can think off. Hoewever, hubby had the same symptoms for a couple of days, and I've heard there's a stomach bug making the rounds. Hope that's what it is!

And I hope you feel better soon.
