Suspected appendicitis but ultrasound couldnt find appendix. does it mean i dont have? and theres no appendicitis ?

It is likely an anatomic variant, test is highly technician dependent, your appendix is not likely to be the cause for your symptoms, followup with pediatrician and//or primary care doc is needed to continue work up in case pain persists.

There is more than one cause of symptoms that are similar to those of appendicitis. Inflammation of terminal ileum, cecum and Meckels' diverticulum can produce similar symptoms.
