Your doctor will review your medical history, especially any digestive illnesses. Your doctor will ask about your current digestive symptoms, including details about your most recent bowel movements: the timing, frequency, character (watery or hard), and whether the stool was streaked with blood or mucus.
Your doctor will examine you and check for pain in your lower right abdomen. After the physical examination, your doctor will order blood tests to check for signs of infection and a urinalysis to rule out a urinary tract problem. Your doctor may order an ultrasound or computed tomography (CT) scan
to help confirm the diagnosis.
Most people will seek medical attention within 12 to 48 hours because of the abdominal pain. In some cases, a low level of inflammation has existed for several weeks before a diagnosis is made.
