Hi,
This depends on few more factors- the approximate frequency of episodes, duration of each episodes, any associated symptoms and impact of
fever on her overall growth and development. If it is just once in 2-3 months, without any other associated symptoms (except for minor cold/cough), clears in 3-5 days, active and playful during episodes, feeding as usual and she is growing normally with normal weight and developmental milestone, I wont be worried.
If I were your treating doctor, apart from the above said tests, after examining for pallor, generalised
lymph node enlargement, rash and enlargement of liver/
spleen, I would have ordered an ESR, peripheral smear and an
ultrasound abdomen (to look for any hematological / inflammatory disorder and hidden abscesses) and proceed accordingly. Your doctor will guide you. It is better to stick on a single
pediatrician for further follow ups. This will help further workups needed to be systematic.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Muhammed Aslam TK, Pediatrician
