Dear Tina, I dont know the most important thing; how old is you daughter? Symptoms u re describing can be related to appendectomy
complication especially if it was perforated and pelvic type of appendicitis
. It seems like ureter
was irritated which is a common complication and urinary infection should be ruled out definitely. Abscessus collection after appendectomy which US is describing could cause such symptoms, and it must be treated by antibiotics. Percutaneous puncture of collection can be also done if neccesary but i suggest just to wait for the effect of antibiotics. If febrility and pain persist then u should repeat CT scan
. Also i think that you shouldnt give analgetics to child because it can hide symptoms, be care about it...you must know the intensity of pain no matter how it hurts because it guides doctor to the right diagnosis.
Wish you good health, dr.Ivan Romich (Rominho)
