Sir I have gone through your query.
It suggests that you may be suffering from the eustachian tube dysfunction
For this you may add with prednisolone-
1. Mucolytics such as acetyl cysteine
2. Steam inhalation.
3. Chew gum containing xylitol such as happydent.
Please consult the ENT specialist
before taking these medicines for better management.
Wish you good health
