Hello and welcome to healthcare forum.
As you said, that your daughter is having pain at right side of abdomen usually without temperature, most probable diagnosis would be renal colic
Other differential diagnosises would be mesenteric lymphadenitis
and subacute appendicitis
. To confirm the diagnosis your daughter will require ultra sonography
and some routine blood investigation.
After that consult a surgeon with her reports for further guidance.
Best of luck.
