How to determine if i have appendicitis?

See a doctor: Progressively worsening right lower abdominal pain over 24-48 hours with nausea and sometimes vomiting and fever. Would need to see a doctor for an evaluation.

If worried, see doc: The classic symptoms of appendicitis are abdominal pain localizing to the right lower quadrant (rlq) of the abdomen, some nausea & vomiting, & lack of appetite. On exam, there will be tenderness in the rlq. If the appendix has ruptured, pain & tenderness may be throughout the abdomen. Labs generally show elevated white blood count. Abdominal ultrasound or ct scan are increasingly used for dx.
