Starts out as pain in your lower abdomen - about 3 to 4 inches to the right of your bellybutton. You might feel like you've got a bad stomach ache. It can also feel like you have been doing way too many sit ups! The pain will steadily get worse and worse over time.
It will be a severe pain in your lower abdomen. If you can jump, you probably do not have a burst appendix. If you are in so much pain that you cannot stand up straight or jump, you should go to the hospital immediately.
