[|AI|]  Hi. Thanks for your query and an elucidated history. You are getting this problem either due to a surgical condition like appendicitis or diverticulitis which gets sometimes aggravated. Another possible reason is that you may suffering from a condition called irritable bowel syn Chat Doctor. . IT is always a better idea to get an opinion and clinical examination by a Gastroenterologist, to undergo the investigations as per his orders. I would suggest you to undergo contrast enhanced CT scan done along with ultrasonography and color Doppler studies.
