This is Dr. D.J., experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Bacterial infection is certainly possible given your chronic post nasal drip.
And the infection can spread to the middle ear cavity causing inflammaton.
There can be ear effusion or fluid in the ear as well.
The eustachian tube connecting the middle ear and the throat can get blocked.
This can result in ear fullness and hearing problem.
Now, Keflex should help and the dose is 4 tablets daily for 7 days.
But, there is also another possibility --allergic responses.
Steroids are good to resolve that in this case.
Steroid is strong anti inflammatory and helps to reduce fluid and unclog the ears.
Prednisone can be used orally.
Or, Fluticasone nasal spray can be used daily which also requires prescription.
There can be trauma to the ear drum causing conductive hearing loss.
This can be checked by the ENT specialist.
However, your current symptoms are likely due to the ear effusion and eustachian tube dysfunction.
For this besides antibiotic, steroid course should be considered for faster resolution.
yes prednisone is much more effective definitely.
