Hi Doc,
My Son aged 8 often experiences elevated forehead temperature than the rest of body.
His head temperature is sometimes around 37.5 to 37.7 deg C while rest of body including ears are at 37 degrees C. He is 127 cm and 23 kg and can not take anything in breakfast with little water intake per day.
This temperature difference between body and head is challenging to find a plausible answer.
Thanks for your time and please feel free to ask any further details.
