So I've had IBS for quit awhile. Like many of you I experience a lot of stomach pain after eating and such like cramping, bloating, diarrhea, and my body goes numb. However, the past 3 years I've experience an exercising pain in the lower left stomach kind of above the kidney. Anyways it'll start after a few minutes of exercising like say 15 jumping jacks. The pain is like a fist clenching ball that feels like a knife going through. A lot worse then a regular side ache. The weird things is sometimes it happens and sometimes it doesn't. And I'm not able to pinpoint the food/reason. Anyone have this.Also, does anyone get really bad bloating/cramping/gas just walking around such as in a mall.
