Last night I started having abdominal pain. The pain appeared around the navel and comes and goes—roughly every 30 minutes. It hurts and stabs for about a second, about 10–15 times, then goes away. At night my temperature was 98.4°F. During the day, it was normal. I tried pressing on the abdomen in the area where appendicitis is usually felt—it hurts a little, but the pain sometimes radiates to the left side. Could this be appendicitis? We will go to the doctor tomorrow if the pain continues.
