Signs and symptoms of appendicitis may include: 1  Sudden pain that begins on the right side of the lower abdomen. 2  Sudden pain that begins around your navel and often shifts to your lower right abdomen. 3  Pain that worsens if you cough, walk or make other jarring movements.  Nausea and vomiting.
The main symptom of appendicitis is belly pain. Many people feel the first pain near the belly button. Then it moves to the lower right side of the belly. But the pain can be in different parts of your belly or even on your side or back. The pain may get worse if you move, walk, or cough. You may also have a fever or feel sick to your stomach. In some cases, appendicitis doesn't cause any symptoms except for belly pain. The pain in your belly may be different than any pain you have had before. It may be severe. Or it may not seem like a very strong pain, but you may have the feeling that something is wrong.
