Doctor can evaluate: If one has some uncomfortable tummy pain, and is normally in good health, some possibilities include: appendicitis (usually lower right tummy), diverticulitis (usually left tummy), kidney stone (very painful), constipation (crampy on left), tumors, intestinal infections, etc... A person with more than brief, mild pain needs a doctor's evaluation to be sure it is not something serious.
