What Causes Fever After Tonsillitis Treatment?

my son started cefalexin for tonsillitis and despite having had four doses still running a pyrexia of 39c. Paracetamol and ibuprofen (alternately) only bringing temp down to 38c.
Is it normal to still run temps after 24hrs of antibiotics? He is ??sensitive to penicillin hence why he is on cefalexin.

HI
Well come to HCM
I really appreciate your concern, two possibilities are there one is this could be resistance case for "cephalexin" so antibiotic need to be changed and second this must be something else and not "Tonsillitis" in such situation it is better to get done the routine blood test, for differential diagnosis, "Typhoid need to be ruled out" hope this information helps, take care.
I find this answer helpful
