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