you get pain in your right side sometimes it can be on your left or near you bellybutton. you have a fever and throw up. when you walk you will be bent over and it hurts like hell. the test they do is take blood or do a rebound test which is pushing in the area and releasing real fast. if it hurts when they release but not when they push there ya go. go get it out now it can get gangrene and rupture then bad things can happen to you...good luck with this hope it isn't what you have.
