Welcome to HCM,
Pain in the throat can be referred to ear, because of the communication between throat and the ear. The infection from the ear can easily reach the ear and can cause infection in the ear.
Whenever there is a infection WBC
should be increased, i donot know what blood teat you undergone.
I would suggest you to take
A course of oral broad spectrum antibiotics
Still if your condition is not improving you may consult your ENT surgeon for physical examination and treat appropriately.
