My son has had a fever on and off for the past week,,,he also complains of a sore upper tummy, all of this began with a headake. i mangaged to keep im comfortable with pamol and ibuprofen until Lastnight I checked on him his temprature spiked to 40.5. I then used paracetamol suppositories the docotor gave me when he fell sick sometime with the identical symptoms....after the long hour of nursing his fever it came down....my main question is "is it really a viral sickness or is it something more serious? my son has a history of nephrotic syndrome..please help i feel his doctor is missing something!
