so really what your question is - its not about fevers. fevers are nothing but a reaction.
the key here is sore throat. almost too painful to swallow. and along with that comes a fever.
foods dont reduce fever. tepid water baths reduce fever. putting a cool washcloth on hot points like behind the knees, behind the neck reduces fevers. not being bundled up reduces fever.
now for us in our family we have a tendency to get high fevers. so for me a 104 does not bother me. however a 101 would bother me if dd acted sick. however i would say for me i worry about a low nagging stomach ache more than i do about fever. it means something in her diet is affecting her and its really tough to find.
dd usually gets a nasty sore throat without fever. i do nothing. i up her water and greens and do soft foods
so i'd say dont worry. it seems in your case the doctor is the best way to go.
in the meantime i'd up her natural antibiotics in her diet and see if that makes a difference. things like garlic http://www.steadyhealth.com/articles/Natural_Antibiotics___Foods_that_Work_as_Antibiotics_a979.html
i'd cut out all dairy and see if that affects her colds. try it for 3 weeks at least (it usually takes i've been told 3 weeks to take anything completely out of your system).
and for sure - i'd make sure she is getting enough water - not liquids - but plain water.
