Doctor can evaluate: One's primary care doctor can check to see if there is a mass of some kind in the abdomen or pelvis, a blockage or other problem with a kidney, an intestinal problem such as diverticulitis, or even a bad case of constipation. Sometimes an infection, diverticulitis, an unusually-located appendicitis, a gynelogical problem, or some sort of tumor, can cause such symptoms.
