Symptom appendicitis. Appendicitis starts, progresses, with pain in lower right abdomen, fever and signs of infection. By 12 to 24 hours patients know something is wrong and get in to a health care facility. Surgeons remove the bad appendix, hopefully before it ruptures. Surgically cured! Recovery is about a week. Usually one or two days in hospital. Often performed laprascopically.
RLQ ABD Pain. The "classic" pt: vague abdominal pain that 'moves' to the right lower abdomen over ~24hrs, becoming constant, progressively worsening; decreased appetite, nausea, vomiting, fever. Studies have shown that only 50% of patients have classic symptoms, making the diagnosis somewhat challenging. Ct scans have been very helpful for diagnosis in equivocal cases, but the radiation exposure is not trivial.
