There are always unasked questions in medicine. Patients visit the doctor for care with a complaint, but under the surface there is always more. If the doctor doesn't anticipate and answer what wasn't asked, then the patient leaves the office worried, unsatisfied, and upset. Arrive complaining of a headache, and the doctor offers pain medication, but you want to hear the words "I don't think this is a tumor or a stroke." Have chest pain? You want reassurance that you aren't having a heart attack.
Roy Halladay (pitcher for the Toronto Blue Jays) was probably unhappy that his stomachache was really something serious - appendicitis. A little belly pain and the next thing you know, you're in the operating room and being told that you won't pitch again for 6 weeks; all because of a little string of tissue called the appendix. This addendum to the cecum, the area in the right lower part of the abdomen where the small intestine joins the large intestine or colon, causes great worry for doctors and patients alike. The pattern originally described by Dr. McBurney of pain developing around the belly button, followed by nausea, and then having the pain move to the right lower quadrant has been explained in medical textbooks forever, but unfortunately not every patient has read the book.
The appendix is a hollow little tube and can

The problem with diagnosis is not the patient who presents classically with symptoms and signs such as:
It's everybody else, who may not have the classic symptoms and signs. Appendicitis may mimic ovarian cyst pain in women who ovulate, or a kidney infection if the appendix is hiding by the kidney. Other diseases also may mimic appendicitis.
So how is the doctor supposed to answer the unasked question? Before technology brought us computerized tomography or CT scan, people had appendectomies (operations to remove the appendix) because there was a worry that the appendix was inflamed and to prevent the possibility of rupture. It was accepted that the surgeon would take out a normal appendix 15%-20% of the time. But in those patients where uncertainty exists, the surgeon may rely on the CT scan to look inside the abdomen and decide whether the appendix is inflamed or if something else is causing the symptoms and signs.
But not everybody needs a CT, and the scan is not always helpful. It takes 6-12 hours after the onset of symptoms for enough inflammation to show up on the CT. And in an awkward twist, thin people are at a disadvantage over those with extra body fat, because more fat allows better visualization of tissues in the abdomen. So sometimes the CT can't help because you can't see the appendix. Fortunately, the art of medicine is practiced alongside the science, and time is often an ally. In people in whom the diagnosis is in doubt, watchful waiting may sort out the diagnosis. Ultimately the doctor has to decide whether the patient has a surgical abdomen (a need for surgical exploration) to determine the cause - or decide that the abdomen is benign (no surgery), and time will cure whatever ails the patient.
