[|AI|]  Hi. Thanks for your query and an elucidated history. Understood the history. CT scan and blood tests are normal. Pain in abdomen on the left side in a person of 72 years of age with normal CT and blood work and no blood in the urine can be due to constipation, stricture of the colon. This can be diagnosed only by Colonoscopy and biopsy as most of the other condition of kidney and pancreas can be diagnosed by CT scan which is normal. A good clinical / physical examination by Gastroenterologist, preferable a surgical one can clinch the diagnosis.
