as of now, the gold standard treatment of appendicitis
remains a removal of the appedix. Pain around the appendicular area does not always imply that it is appendicitis. Based on clinical findings, blood tests and an abdominal ultrasound
might all be needed to make such a diagnosis. However, in emergency situations, this diagnosis can be made barely on clinical grounds.
Considering the onset of your pain and response to treatment, it might be as well as not appendicitis. If it were appendicitis, good practice is to do further testing with additional blood tests and an abdominal ultrasound to actually prove. Decline or apparent state of well being depending on drug type might not imply real cure, and might simply mitigate symptoms to present in a later stage with complications such as an appendicular abscess
or a perforation.
I suggest you meet your general or visceral surgeon for a consultation, get an abdominal ultrasound and appropriate blood tests, for a clear cut diagnosis to be made and establishment of a follow up plan,
Thanks as I pray this helps,
