The Jumping Up Test: Easier Diagnosis of Acute Appendicitis in Children

My parents knew about "you can't properly raise your right leg" home test.
While ER folks - well first ones in the evening were crap and basically sent me home to see if it will pass.
Then in the morning (yeah it didn't pass, and I don't think I've slept much because it felt like a bad tootache in your stomach) other ER doctors checked: - 1 Celsius or more higher temperature rectally compared to armpit - push fingers at general area of appendix on your stomach hurts like any other pain (say bad stomach, having been hit ...etc) there would hurt, releasing the pressure slowly is fine and gradually reduces the pain, while quick/snap release of pressed spot felt like you've just been stabbed with a knife (well OK how one would imagine that feels).
And within minutes they accepted me into hospital and I was operated within few hours.
And I guess jump is doing similar things to muscles and tissues since it's quick/explosive type of movement.
Also - and it's been ~20 years so memory is fuzzy - I think doctor explained/mentioned exponentially larger pain on quick release of press compared to slow pressing and even just holding same pressure for longer is general sign of inflammation, not just apendix.
