Sometimes after a normal BM I feel like my abdominal sides cramp and hurt. Colonoscopy normal. Been SIBO free for a year. Am wondering why?

Alarm signs to check. Maybe IBS; maybe not GI. Recurrent abdominal discomfort is first addressed by accompanying signs/symptoms that may localize the organ involved: vaginal discharge or bleeding, alteration in periods, pregnancy risk? Fever, nausea, vomiting, altered stool pattern, blood with stool, tenderness, distension? Painful urination, blood in urine? Recent trauma, herniations? Risk factors? Other tests done?
