Persistence of the symptoms you present with suggest chronic sinusitis
. The sinuses
, the ear and the throat are structures which are interconnected, and an infection in one area easily contaminates the other. Appropriate antibiotics are required for these infections. In your case, specific X rays of the sinuses is advised to be done to exclude any pus collection in any of these sinuses. However, consulting an ENT specialist
for a proper examination of your ears and throat should be considered.
Hope this helps and best regards,
