My son had a tonsillectomy and partial adenoidectomy a week ago today and is still running a low grade fever?

Actually, the back of the throat looks rather cruddy for two weeks after tonsillectomy, and there probably is a low grade infection at the operative site. So a low grade fever is not unusual. But other things can take place. I once removed a small cotton pledget that was stuck in the tonsillar pillars one week after tonsillectomy. It had allowed an infection to smolder. Removing the foreign body was associated with cessation of the fever. If the child is coughing, it is possible that a small piece of tonsillar tissue was aspirated into the lungs. This does not happen so much these days with newer anesthetic and surgical techniques.

Yes. When you chart BBTs, you become aware of an develop in temp after being pregnant. I would not be involved except it is over one hundred. Low grade fever (some thing under one hundred) isn't a trouble for contamination or a motive to transport your appt up. If you're quite involved, then name your doctors workplace and ask for a nurse to name you again and speak to you.

Please have your son re-examined by his head & neck surgeon (ENT=ear/nose/throat surgeon).

That will provide you with the best peace of mind and reassurance.

That is something you should be discussing with the surgeon.
