For how long is an appendix typically sick before symptoms of appendicitis?

12 hour/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.
