I have gone through your query.
It suggests that you are suffering from the bacterial sinusitis
with Eustachian tube dysfunction
In this condition I personally advised to you-
1. Proper antibiotic course.
2. Nasal decongestant.
3. Systemic decongestant.
4. Steam Inhalation.
For better diagnosis and management consult your ENT specialist
If you have any doubt, I will be available for query.
Wish you good health
