My 9 y/o has had enlarged tonsils since Jan without strep , fever that persists and won t go away for more than 2 days. Her doctor yesterday said no signs of infection and said maybe allergies. She took Claritin as prescribed and has been sleeping all day, now has a fever again. Other than a sore throat and headache she feels fine. Can allergies do this?
Hi, I am Chat Doctor.  Allergies in some persons can be enough to cause swollen tonsils (tonsillitis). If that is the cause then clarity will be fine (sleepiness is one of its side effects). However, if she is developing a fever again, then one has to full out an infectious cause (bug) or some local complication of the swollen tonsils such as an ear or nose infection for a swollen tonsil can prevent normal aeration of these structures or
