Welcome to HCM.
Based on the symptom i think she might be suffering either from upper respiratory tract
infection / tonsillitis
I advice you to do warm salt water gargling 5 to 6 times a day. Ear pain might be due to blocked Eustachian tube
, it will be reduced by steam inhalation.
I advice you to follow the above mentioned approach, if it does not help i advice you to see ENT specialist
for examination and exact diagnosis.
Hope I have provided the information you needed.
Wish you good health. Take care.
