I Have A Chronic Abdominal Cramps Associated With Exercize And

I have a chronic abdominal cramps associated with exercize and multiple bowel movements each day that seem to decrease the gerd type stomach reactions as well as cramps when I try to walk, run, ride a bike, or swim. I have had two endoscopy and two colonoscopies and found no problems. I have a hiatal hernia. Currently taking Pantoprozle, ranitidine, and stool softeners twice daily. Symptoms persist especially in the morning before bowel eliminations. These are daily occurances.
