Answer:
Appendicitis is basically a disease of your appendix, a small organ off of your intestines. If you think you have appendicitis, press quickly down on the area that hurts, then sharply lift up. Which hurts more? If you truly have appendicitis, the lifting up should hurt a bit more. The pain would be in your lower right abdomen, though it can migrate. If you are reading this and you have all these signs, go to a hospital ASAP. You don't want a burst appendix, which will be a lot harder for doctors to clean up. I know all this because I've experienced it.
