Hello. I have had a sudden sharp left side flank pain that radiates to the front just under the rib cage. I have no fever. I have a history of diverticulitis with my sigmoid colon removed and a colostomy pouch. Yesterday I had sharp lower left abdominal pain that felt like it could be from the ovary but that is better today. I have no symptoms of a UTI and did not injure my back. Is this something I should be concerned with today or would it be something that could wait until I can get in with my doctor?
