Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that your daughter is suffering from upper 
respiratory tract infection and the symptoms of earache, 
sore throat and fever are due to it..
As it is a viral infection it will resolve once the virus will complete its cycle in human body..
As of now you can start with supportive treatment to relieve the symptoms like:
-Gargle with a warm saline solution that is by mixing 1 teaspoon salt in a glass of water and warm it to 
make a luke warm solution..
-Take a combination of decongestant like 
Phenylephrine, mucolytic like Ambroxol and anti allergic 
levocetrizine and another combination of 
Acetaminophen and Ibuprofen..
-Take cough expectorant containing Gueifenesin and cough suppressant containing 
Dextromethorphan.
-Chew a Vitamin C pellet daily..
-Do steam inhalations..
-Avoid spicy and chilled foods.. 
In case of no improvement consult a Paediatrician and get evaluated..
Hope this helps..
Regards..
