I think i have appendicitis. when do i go to hospital?

Now is a good time: If symptoms are very mild, it might not be appendicitis. When a person has appenditicis, it is an abscess in the appendix, and it grows bigger, swelling and causing pain. Then the abscess leaks out of the appendix and the pressure inside decreases (a burst appendix), causing less pain. The infection is then in the general abdominal area and will grow, thus needing treatment to avoid a bad outcome.
