I have IBS and Acid reflux.. I have been having a knowing ache in my left side of my stomach about mid way 3 inches or more from the belly button. It happens 5 times a day and last seconds.. But my bowels have been affected too.. I have been stressing big time over bills/ money problems... lost my brother.. I had a KUB xray a few months ago, a endoscopy/colonscopy late 2014. What can this be... I am overweight... had bloodwork a few weeks ago and it was good
